The Magnetic Circuit Protector (MCP) provides an instantaneous trip in the
event of a short circuit or a locked rotor condition. This offers improved
protection for the motor starter, wiring, and motor over standard circuit
breakers. The ampacity is fixed at 50 amps and the magnetic trip setting
is adjustable over a range of 150 to 550 amps. The setting used is relative
to the full load amperage of the motors and is given in the table at right.
Motor overload protection is handled by the motor starter.
