WFCO Power Transfer Switch; 57 Series Description

The T-57 Mounts on flat surfaces as a stand-alone in conjunction with any distribution panel.

The WFCO T-30 and T-57 transfer switches are designed to provide trouble-free changeover of power between shore power and generator. The T-57 is designed for 50-amp AC service, and the T-30 is used for 30-amp AC service.The T-30 can be installed on the back of a WFCO 8900 Series Power Center or like the T-57 it can be easily mounted to any flat surface. The compact design allows for placement in areas with limited space. Both transfer switches are engineered for safe, reliable performance.The DC coil in either unit prevents AC “chatter” noiseand drop-out in low-voltage conditions. Accidental coupling of power from or to shore line and generator is prevented by a “break before make” configuration.

When the T-57 is plugged into the shore power, the T-57 will automatically provide AC power to all AC appliances. To operate your appliances from the on-board generator, simply start the generator and the T-57 will (after 20-30 seconds) automatically transfer the electrical power to AC appliances. The time delay of 20-30 seconds allows the generator voltage to stabilize.
