Westinghouse Electric OT3PF Pushbutton Transformer

The Westinghouse OT3PF Pushbutton Transformer is an industrial control transformer intended for panel-mount installation in control panels, pushbutton stations, motor control centers, and other operator-interface equipment. It supplies a reduced control voltage from industrial control voltage systems for single-phase control circuits, with a 50/60 Hz frequency rating and screw-terminal connections for robust field wiring. This unit is designed for industrial duty and is compatible with pushbutton stations and control panels, providing control power isolation and voltage conversion for safe, continuous operation in manufacturing facilities, HVAC equipment, power distribution, and motor control applications. Typical use includes powering pushbuttons and operator interfaces within industrial automation machinery and MCCs, transforming standard control voltages into a suitable level for control circuitry. Manufactured by Westinghouse, the OT3PF is specifically associated with panel-mounted installations and compatible equipment such as Pushbutton Stations and Control Panels. Common replacements include Allen-Bradley 1497 Control Transformer, Eaton C0500E2A Transformer, and Schneider Electric 9070T Control Transformer.
