Acme Electric TA-1-81214 Three-Phase Control Transformer

Acme Electric TA-1-81214 is a 350 VA industrial control transformer with a 240/480 VAC primary and a 120 VAC secondary, designed for single‑phase control power in electrical panels, automation cabinets, and other equipment that require a safe, isolated 120 V control voltage from higher mains. It is rated for 50/60 Hz operation, enabling reliable use in facilities with either 50 Hz or 60 Hz power without changing components, and the voltage configuration supports both typical North American 120 V control circuits and 240/480 V mains feeding the primary windings. With a 350 VA rating, the TA-1-81214 can deliver up to about 2.9 A at 120 VAC, a capacity sufficient for several common control elements such as relays, timers, and small contactors connected in a panel. The device is manufactured by Acme Electric, a brand under Hubbell, and the TA-1-81214 is consistently cataloged across official Acme Electric literature and distributor listings with identical specifications, confirming its intended use as a control‑power transformer in industrial environments. When selecting this transformer, verify the exact primary voltage option (240 V or 480 V) and ensure your control circuit operates at 120 V to maintain proper voltage regulation and avoid overloading the secondary.
