Industrial TB81210 Industrial Control Transformer

The Acme Electric TB81210 is a 50 VA, Class 130 open-core industrial control transformer designed for single‑phase control circuits in 50/60 Hz systems. It accepts primary voltages in paired configurations of 220/440 V, 230/460 V, or 240/480 V AC and delivers a 110/115/120 V secondary for low‑voltage control devices. Built with copper windings in an open‑core and coil construction, it features integrally molded terminal blocks with isolation barriers and a heavy‑gauge steel mounting plate for easy, secure installation. This transformer is engineered to maintain secondary voltage during momentary inrush when energizing electromagnetic components, making it suitable for powering relays, contactors, sensors, and other control equipment inside industrial panels while keeping primary and secondary circuits isolated for safety. It operates at 50/60 Hz and is a single‑phase, 50 VA device designed for reliable control‑system performance.
