GE Limitamp® Medium Voltage Motor Control General GE manufactures and provides full support for the following types of medium voltage controllers: Table A.1 Product Scope Controllers Design Layout Construction 1-High 2-High Welded Bolted CR194 Stationary Vacuum 800 amp X X CR194 Drawout Vacuum 800 amp X X CR194 Stationary Vacuum 400 amp X X CR194 Stationary Vacuum 400 amp CR194 Drawout Vacuum 400 amp • Limitamp lineup similar to last three units in the preceding description. The transformer, 480-volt motor controllers, and lighting transformer are included in an integrated Limitamp design. X 480V X X X X Lighting Limitamp control is designed to meet NEMA ICS 3, Part 2 and UL 347 requirements. Various enclosure types and constructions are available and there is a broad selection of modifications for complete control and protection of motors used on modern power-utilization systems with high available short-circuit currents. Applications CR194 Vacuum Limitamp control is a high-interrupting capacity, high-voltage control applied to distribution systems rated 2400, 4160 or 4800 volts (7200-volt starters are available in limited applications.) It is used throughout industry to control and protect squirrel-cage, wound-rotor and synchronous motors. It can also be used to feed transformers and other power-utilization circuits. • Limitamp lineup consisting of a reversing isolating switch ahead of a NEMA Class E2 Limitamp motor controller. • Limitamp lineup consisting of two NEMA Class E2 Limitamp motor controllers, each having interrupting ratings per Table B.1. Typical applications are in paper, steel, cement, rubber, mining, petroleum, chemical and utility-type industries. Limitamp control is also used in water and sewage plants and public buildings for air conditioning, pumps and compressors. Because of its flexibility, other uses for Limitamp equipment have become common. Some of these uses are: • Limitamp lineup consisting of a fused isolating switch ahead of four NEMA Class E2 Limitamp controllers, the first three being used as motor controllers and the last as a transformer feeder. CR194 control is designed for operation on the following power systems.
