I-T-E Max-FlexTM Flange-Mount Handle Operator
Types 1, 3, 3R, 4, 4x, 12
Application
The Max-Flex Operator is designed to work with I-T-E circuit
breakers having current ratings through 600A. The Max-Flex
unit meets all the industrial criteria such as UL and Automotive
Industry Standards.
Design
GENERAL INFORMATION
The new Max-Flex Handle Operator provides maximum flexibility in design and assembly of electrical equipment. Since
there are no linkages to assemble, the Max-Flex system can
save time during installation.
Description
The I-T-E Max-FlexTM Flange-Mount Handle Operator is a
flexible cable control device used for the remote switching of
a circuit breaker within an enclosure. The flexible cable is
connected directly to the breaker switch handle at one end
and a factory installed switch handle operator at the other end.
The remote operator handle, located on the enclosure flange,
is used to perform mechanical open/close switching operations. This is accomplished through the cable’s sliding center
race enclosed within the cable.
Function
The advanced design concept of the Max-Flex Handle Operator provides for greater flexibility when locating a circuit
breaker within an enclosure. The circuit breaker can be
mounted almost anywhere, at any angle and on almost any
convenient surface. The same flexibility applies when locating
the switch handle operator on the flange section of the
enclosure.
The cable design is flexible and rugged. It is similar to those
cables used in aircraft control systems. The flexible cable
comes in standard 3 or 4 ft. lengths. However, specific lengths
can be special ordered up to 20 ft.
Operation
When properly installed, the Max-Flex Handle Operator is
used to perform remote switching operations from outside of
the enclosure. Switching is accomplished by pushing the
Max-Flex Handle Operator up for ON and down for OFF. The
mechanical advantage gained with this device simplifies switching operations when compared with local switching at the
breaker.
This unique design offers breaker trip indication as a standard
feature. Interlocking provisions are included and described
below. All switching functions are standard to accepted
practices.
