CONTACTOR (P/N 111cco1ay1) - New Surplus

The 111cco1ay1 is an electromechanical contactor that switches high-current DC circuits in aircraft electrical systems. This power relay controls battery distribution and main bus connections, engaging and disengaging based on coil voltage signals from flight control circuits. Built to MIL-PRF-6106 aerospace standards for environmental and electrical performance, it handles the demanding thermal and vibration conditions of aircraft powerplant installations.

Installation requires qualified personnel to secure the contactor per aircraft maintenance manual specifications, matching coil voltage and terminal torque requirements to ensure reliable power management during all flight phases.
