The overload trip relay is mounted next to the limitswitch and consists of a plunger actuated by an armwhich lifts at a predetermined current in the trip relay is calibrated in five steps at 100-amp intervals,starting with 450 amp which is approximately twice theone-hour rating of the motor. Contact disks on theplunger open the control circuits to all switches, andthese circuits are re-established by unlatching theplunger by means of the reset coil, which may be ener-gized by pressing a button in the top of the mastercontroller after th
