Industrial 1155689A Auxiliary Electromagnetic Relay

The Westinghouse Electric Corporation 1155689A Auxiliary Electromagnetic Relay is an industrial control relay designed for auxiliary switching, interlocking, signal transfer, and control circuit interfacing in switchgear and automation panels, with an intended use for control circuit switching and auxiliary relay functions in power distribution environments and industrial automation. It features a 125 VDC coil and auxiliary control contacts (configuration varies by assembly), supports panel or relay rack mounting, and is designed to expand contact capacity while isolating circuits for low-power control. The relay is compatible with Westinghouse switchgear, protective relays, and control panels; it's commonly used in power generation facilities, substations, motor control centers, and industrial plants for signal transfer, interlocking, and control logic operation, with common replacements from Eaton, Siemens, and Schneider Electric.
