Westinghouse Electric Corporation 112D631H04 Transformer

Westinghouse Electric Corporation 112D631H04 is a 0.150 kVA, single-phase machine tool/control transformer that steps 240/480V AC input down to 120V AC for isolated control power in industrial automation, providing voltage isolation between high-power circuits and sensitive control devices to improve safety and reliability. Panel-mounted for installation in motor control centers, industrial control panels, and machinery, it delivers low-voltage power to relays, contactors, timers, pilot lights, PLC systems, and other control devices while keeping control circuits isolated from line voltage. Key specifications include primary 240/480V AC, secondary 120V AC, 50/60 Hz, 1PH, Series MTC, and 0.150 kVA (150 VA); the model is discontinued but commonly available as surplus or replacement stock, with common replacements from Eaton MTC Series, Siemens Industrial Control Transformer, and Schneider Electric Square D Control Transformer.
