Schneider Electric 9070 E0-3 Control Circuit Transformer

Schneider Electric 9070 EO3D1, commonly cataloged as 9070 E0-3, is a single‑phase industrial control transformer in the 9070 family that provides 120 VAC control power from a dual‑primary 240/480 VAC supply. Rated at 150 VA, this EO3 device features dual primary windings configurable for 240 or 480 V and a 120 V secondary for control circuits such as relays, contactors, timers, and PLC inputs in industrial equipment. It supports 50/60 Hz operation and carries an 80°C rise rating for reliable performance in demanding panels and machines. Use of this transformer helps isolate and step down main power to power control electronics while fitting compact panel layouts and standard Schneider Electric control hardware.
