56 MOLDED CASE CIRCUIT BREAKERS Replacement Motor Circuit Protectors REPLACEMENT CAPABILITIES The Motor Circuit Protector (MCP) is designed specifically for the protection of motor circuits. It operates on the magnetic principle with a current sensing coil in each of the 3 poles, with the trip-point adjustable from the front. MCPs are the fastest devices available for clearing low level faults and offer circuit breaker features and convenience, resettable, quick makequick break, dead front, and protection against single phasing. MCPs are rated to correspond to NEMA starter size Current Limiter Attach. (Size 0-4 Only) The EL current limiter is an attachment that bolts to the load end of the MCP to provide increased interrupting capacity. The combination is UL listed as a recognized component for application at up to 200,000 amperes symmetrical at 600 volts AC. It is coordinated with the MCP so that normal short circuits will be cleared automatically by the MCP, opening all 3 poles, and only the rare high fault will cause the limiter to function. Current limiters must be applied as shown in the table below. Terminals Terminals are included with both the MCP and Current Limiter. Standard terminals are aluminum alloy, with non-aluminum terminals optional for use with only the MCP. Both standard and optional terminals will accommodate aluminum or copper conductors. ➊ When using aluminum conductors, use of joint compound is recommended. Wire ranges are listed below.
