Transformers

Transformers ranging from 20VA to 375VA are foot and/or hub mounted. They are available with single or dual threaded hubs. Some are foot mounted only. Most are UL Listed or UL Component Recognized, and many are Class 2. Several transformers are provided with a circuit breaker. Pigtail wires are standard on all models and are up to 9.5" in length. All transformers utilize split-bobbin construction.
