Overview
The Cutler-Hammer C0350E2B is a 350 VA single-phase industrial control transformer designed for reliable power conversion in automation, PLC, and motion control systems. This MTE-type (Midget Transformer Encapsulated) unit features dual input windings rated for either 240V or 480V AC primary voltage, stepping down to a 24V AC secondary for control circuits. Operating at standard 50/60 Hz frequency, the transformer is ideal for supplying power to HMIs, PLC modules, relay logic, and solenoid control networks in industrial manufacturing and process automation environments.
