Westinghouse 1351D18A01 IT Electromechanical Relay

The Westinghouse 1351D18A01 IT Electromechanical Relay is a low-current protective relay rated at 0.2 A, designed for current-responsive monitoring and protection in industrial and utility power systems. As an IT protective relay, it provides current sensing and protective relay operation within switchgear, substations, transformer protection circuits, and control systems. The device uses electromagnetic relay actuation and is intended for panel or relay rack mounting in industrial, commercial, and utility environments as a protective relay assembly. Its protection type covers overcurrent and monitoring functions, enabling fault detection, alarm initiation, and coordinated circuit-breaker tripping to protect equipment and maintain system reliability.
