Allen-Bradley X376737 Voltage Transformer

Allen-Bradley X-376737 voltage transformer is a 1‑phase control transformer rated at 150 VA, designed to connect a high‑voltage primary to a 120 V secondary for control circuits in industrial equipment. It lists a primary voltage of 550/600 VAC and a fixed secondary of 120 VAC, and operates on 50/60 Hz power, making it compatible with standard plant supplies. This 150 VA unit provides galvanic isolation between its primary and secondary and is commonly used to power relays, PLC I/O modules, timers, and other low‑voltage control devices within control panels or machine tools. The model is widely documented under the Allen‑Bradley X‑376737 (also seen as X376737) designation by multiple distributors, reflecting its role as a compact, single‑phase 600 V to 120 V control transformer in automation environments.
