Westinghouse 112D631H04 Control Transformer With Fuse

The Westinghouse 112D631H04 is a panel-mounted industrial control transformer with an integrated fuse block that steps 240/480 VAC (230/460 VAC) down to a safe 120 VAC (115 VAC) control voltage for relays, contactors, PLCs, timers, and other machine-control circuits. Rated at 0.150 kVA (150 VA) and single-phase, it operates at 50/60 Hz and is built for machine tool and general automation applications in motor control centers, industrial control panels, machinery, conveyors, packaging equipment, HVAC systems, and other industrial automation equipment. The fused configuration protects downstream control components and simplifies panel wiring by providing isolated, low-voltage power for control circuits. This model, part number 112D631H04 from Westinghouse Electric Corporation, is discontinued by the manufacturer and commonly available as surplus or replacement stock.
