Industrial 112D631H04 Control Transformer 0.150 kVA

The Westinghouse 112D631H04 Industrial Control Transformer is a 0.150 kVA (150 VA) single‑phase machine tool / control transformer designed for voltage step‑down and isolation of control circuits in automation and electrical control systems. Part of the MTC Series, it is panel-mounted for installation in motor control centers, industrial control panels, machinery, and automation equipment that require dependable isolated low‑voltage power for relays, contactors, timers, pilot lights, PLC systems, and machine control circuits. Primary voltage options are 230/460 V AC or 240/480 V AC, with a 115/120 V AC secondary and a 50/60 Hz frequency rating. This transformer supports continuous‑duty operation in industrial environments, delivering reliable control power while maintaining voltage isolation between power and control circuits. Status: discontinued manufacturer model commonly available as surplus or replacement stock; common replacements include Eaton MTC Series Control Transformer, Siemens Industrial Control Transformer, and Schneider Electric Square D Control Transformer.
