The exceptional short-time rating of 75,000 A in a 3000 A frame and 100,000 A in a 4000 A frame and above allows the circuit breakers to be fully selective up to their interrupting ratings. 100% Rated The circuit breakers are designed for continuous operation at 100% of their current rating. Other Performances The UL 489 and UL1066 (ANSI C37-13) standard performance tests assure that the circuit breaker has sufficient characteristics to be used in normal conditions. However, the circuit breaker exceeds, without additional costs, the UL standard 1,500 operations required in endurance. The heavy-duty mechanism and the contact design provide a mechanical endurance of 10,000 operations (approx.) without maintenance (see page 64). Tropicalization The standard moisture and fungus protection ensure normal operation under extreme ambient conditions. MASTERPACT circuit breakers comply with T2 tropicalization (IEC Standard 68-2-30); relative humidity 95% at 113°F (45°C) and 80% at 131°F (55°C) (hot, humid climate). Salt spray resistance as per IEC 68-2-11. Poles The 4-pole version is an efficient solution to ground fault problems created by incorrectly grounded standby generators and incorrect transfer switching systems. By isolating the neutral of multiple sources coupled together, 4-pole circuit breakers prevent ground faults from returning to the source via unintended paths. Where unintended paths exist, ground fault sensing can become inaccurate or create nuisance tripping.

Therefore the circuit breaker can be disconnected without opening the door and accessing live parts. Safety shutters can be provided as an option for protection from live parts when the circuit breaker is removed. Connected Position Test Position Disconnected Position True Two-step Stored Energy Mechanism The closing time is less than five cycles. The circuit breaker is operated via a stored-energy mechanism which can be manually or motor charged. Closing and opening operations can be initiated either from the local push buttons on the circuit breaker front face or by remote control. O–C–O cycle is possible without recharging. Designed for No Maintenance... The circuit breaker has fewer parts (by a factor of at least five) than conventional circuit breakers while performing the same functions. This leads to greatly enhanced reliability and reduction in maintenance. Under normal operating conditions, according to standards and controlled by tests, the circuit breaker does not require maintenance. …But Exceeds Standards with an Easy and Reduced Maintenance 06313006 06313007 It is easy to remove the arc chutes and visually inspect the contacts and wear indicator. The operation counter (spring-charging motor option) can also indicate when inspections and possible maintenance should be done. After operating conditions exceeding those given by standards, it is possible to extend the circuit breaker life by: n Replacement of arc chutes and spring charging motor by the user. n Replacement of main contacts by an after sale service team.

Front Connection of Secondary Circuits 06313010 All accessory terminals are located on a connecting block which is accessible from the front even with the circuit breaker in the test or disconnected position. This is particularly useful for field inspection and modification. 4 ©1995 Square D—All Rights Reserved 11/98 Advantages Disconnecting through Door The racking handle and racking mechanism are accessible through the front door cutout. Disconnecting the circuit breaker will therefore be possible without opening the door and giving access to live parts. Isolation Function by Positive Indication of Contact Status The mechanical indicator is truly representative of the status of all three main contacts. Segregated Compartment Once the front cover has been removed to provide access to the auxiliary compartment, the main contacts remain fully isolated. Furthermore, interphase partitioning allows full insulation between each pole even if the front cover has been removed. Reinforced Insulation 06313011 Two insulation barriers separate the front of the circuit breaker from main circuits. 5 11/98 ©1995 Square D—All Rights Reserved Description 2 Description 3 06313012 1 4 5 13 12 6 11 1.

Such faults can be due to repetitive motor startings, fluctuating load or subsequent closing after a fault. I1 I2 I3 90% STR 58 U 50% Traditional electronic protection has no effect when facing such repetitive faults because the duration of each overload above the pickup setting is too short to achieve effective tripping. Nevertheless, each overload involves a temperature rise in the installation, the cumulative effect of which could lead to overheating of the system. 20% Ir xIn tr xIo Im at 1.5Ir tm xIo t Principle I xIn Ih i Ic1 th T Ic2 R DANGER xIn HAZARD OF ELECTRICAL SHOCK, BURN OR EXPLOSION. test xIr xIr F test Use "min" position for emergency only when closing on fault is absolutely necessary. Failure to observe these precautions will cause death, personal injury or electrical shock. 06313184 06313183 The thermal memory function remembers and integrates the thermal heating caused by each pickup setting overrun. Before tripping, the integrated heating value will reduce the associated time delay and, therefore, the reaction of the control unit will be closer to the real heating of the power network system. After tripping, the memory will also reduce the time delay when closing the circuit breaker on fault.

Neutral Ground-fault Neutral CTs S1 T1 S2 T2 Zone-selective Interlocking (ZSI) Option Z on the STR58U control unit provides selective interlocking on short time or ground fault. A pilot wire links several trip units in the distribution network, as shown in the opposite figure. In the event of a fault, the trip unit will respond to the preset delay only if receiving a signal from the downstream unit. If not receiving a signal, the tripping will be instantaneous. Therefore, the fault is cleared instantaneously by the nearest circuit breaker: the thermal stresses (I2t) in the network are minimized, without any effect on the correct time-delay coordination in the installation.

Turn OFF all power supplying the equipment before installing or removing circuit breaker. Failure to observe these precautions will cause death, personal injury or electrical shock. CAUTION HAZARD OF EQUIPMENT DAMAGE. Since circuit breakers contain factory-sealed and calibrated elements. Do not break seal. In case of malfunction, repairs must be made at a Square D factory or by an authorized company representative. Failure to observe this precaution can cause equipment damage. Recommended Inspection Intervals MASTERPACT circuit breakers are designed to be maintenance free (see page 64). However, all equipment with moving parts requires periodic inspection to ensure optimum performance and reliability. It is recommended that the circuit breakers be routinely inspected six months after installation, followed by an annual inspection. Intervals can vary depending on particular use and experience. Inspection of Circuit Breaker Terminals n Inspect terminals; if there is discoloration due to overheating, the joint should be disassembled and the surface cleaned before reinstallation. It is essential that electrical connections are made carefully in order to prevent overheating. n Check for terminal tightness. Inspection of Main Contacts The arc chutes are easily removed to allow access to the main contacts and to the wear indicator. The wear indicator consists of a groove located within the contacts support (see page 3). When the circuit breaker is closed, this groove is entirely covered up by the moving contacts. Over time, the wear of the contacts will make the groove appear. When the groove is fully visible, replace the breaker or have an authorized service center change the contacts. Inspection of Clusters Totally maintenance free, they have to be replaced only after overheating due to a defective connection or after a major fault. Inspection is advised when checking the terminal connections. Cleaning Remove any dust and dirt that may have accumulated on the circuit breaker surface and terminals. Mechanical Checks For long periods circuit breakers may not be required to operate on overload or short-circuit conditions. Therefore it is essential to operate the circuit breaker periodically to avoid mechanical gumming. 62 ©1995 Square D—All Rights Reserved 11/98 Appendix Insulation Resistance Tests When circuit breakers are subjected to severe operating conditions, an insulation resistance test may be performed as indicated in NEMA standard publication No. AB4-1991. An insulation resistance test is used to determine the quality of the insulation between phases and phase-toground. The resistance test is made at a dc voltage higher than the rated voltage to determine the actual resistance of the insulation. The most common method employs a "megger" type instrument. A 1000-volt instrument will provide a more reliable test because it is capable of detecting tracking on insulated surfaces. Investigate resistance values below 1 megohm. The insulation test shall be made: n Between line and load terminals of individual poles with the circuit breaker contacts open n Between adjacent poles and from poles to the metallic supporting structure with the circuit breaker contacts closed This test may be made with the circuit breaker in place after the line and load conductors have been removed, or with the circuit breaker bolted to a metallic base which simulates the in-service mounting. Electrical Tests These tests require equipment for pole resistance measurement and for overcurrent and instantaneous tripping in accordance with NEMA Standard publication No. AB4. They are not within the scope of normal field operation. 63 11/98 ©1995 Square D—All Rights Reserved Appendix Endurances A–Endurance Without Maintenance MASTERPACT MP or MC Mechanical Electrical 08 12 16 20 25 30 - 32 40 50 63 12,500 10,000 10,000 10,000 10,000 10,000 5,000 5,000 5,000 480 Vac 10,000 10,000 10,000 9,000 8,000 4,000 3,000 3,000 2,000 600 Vac 10,000 10,000 10,000 7,000 6,000 2,600 2,500 2,500 1,500 20,000 15,000 15,000 15,000 10,000 10,000 10,000 B–Endurance With Service Maintenance Electrical (480 Vac) or Mechanical 20,000 20,000 C–Endurance Required by Standards Frame size UL489 800 Mechanical 3,500 Electrical ANSI 500 1200 1600 2000 2500 3000 4000 5000 6300 2,000 2,000 2,000 2,000 1,500 1,500 1,500 1,500 500 500 500 500 400 400 400 400 Mechanical 12,500 NS 4,000 4,000 NS 1,500 1,500 NS NS Electrical NS 800 800 NS 400 400 NS NS 2,800 Important Notice: All endurances given are based on normal operating conditions and conventional tests: n Closing and opening operations at rated current n Power factor: 0.75–0.80 As actual conditions differ, use these values only as inspection guidelines and periodically check contact wear. Under normal operating conditions of use, as determined by UL 489 or ANSI Standards (see table C) and controlled by tests, MASTERPACT circuit breakers do not require maintenance. However, these circuit breakers exceed, without maintenance and additional costs, the endurances required by standards. See tables A and C. Service maintenance by a field service representative will extend the endurance according to table B. This service can be performed on site and consists in changing contacts, arc chutes and some other parts. Example: MP16 at 480 V requires no maintenance before 10,000 cycles (mechanical or electrical). Endurance may be increased after servicing at 10,000 operations. 64 ©1995 Square D—All Rights Reserved 11/98 Appendix IEC 947-2 Interrupting Ratings In addition to UL 489 and ANSI C37-13, MASTERPACT circuit breakers comply with the IEC 947-2 Standard as per the table below.
