Westinghouse Electric Corporation 112D631H06 Control Transformer

The Westinghouse Electric Corporation 112D631H06 is a panel-mounted, single‑phase MTC Series control transformer that steps down 480 V AC primary power to 120 V AC secondary to provide isolated, low‑voltage control power for motor control and PLC systems, as well as relays, contactors, timers, and pilot lights in industrial automation. It is rated at 0.25 kVA (250 VA) and operates at 50/60 Hz, making it suitable for industrial control panels, machine tools, and other automation equipment requiring dependable control-circuit power with isolation. This configuration includes KLDR‑1 Class CC fuses rated at 1 A for downstream overcurrent protection of the control circuit. Common replacements include Eaton MTC Series Control Transformer, Siemens Industrial Control Transformer, and Schneider Electric Square D Control Transformer.
