The WFCO T-57 is designed to provide trouble-free changeover of power between shore power and generator. The T-57 is used for a 30 Amp or 50 Amp AC service.
The T-57 mounts easily onto a flat surface and is engineered for safe, reliable performance. The unit’s DC coiled relays prevent AC “chatter” noise and drop-out in low-voltage conditions. Accidental coupling of power to or from the shore line and generator is prevented by a “break before make” configuration.
