Transformer with Input Fuse Block

Transformer with Output Fuse Block

Sealed coils protect against dust, dirt, oil, and moisture. These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays. Also known as control transformers. Choose a transformer with multiple output voltages to simultaneously power multiple devices that require different output voltages.
