Applications

The NEC permits the use of adjustable instantaneous-onlycircuit breakers (MCPs) in motor branch circuits as part of alisted combination motor controller. The MCP and motor controlleract in concert. The MCP provides the disconnecting means andshort-circuit protection, and the motor controller provides theoverload protection.

Adjustable instantaneous tripMCPs have no thermal element. The instantaneous tripcharacteristic is adjustable, providing for placement of the tripsetting just above motor inrush. The MCP clears low-level faultsquickly, ignores motor starting currents and improves coordinationwith motor overload relays.

HMCP

The HMCP is available in Series G-, EG-, JG- and LG-Frames to suitlarger motor applications requiring higher continuous current andshort-circuit performance.
