WFCO RV Transfer Switch - WF78VR

The WFCO T-57 transfer switch changes an RV's AC power source between shore power and a generator and is designed for 50-amp, 120/240V AC service.

Features:

• 30-second nominal transfer delay allows the generator to complete self-diagnostics before power is transferred.
• Break before make configuration prevents accidental coupling between shore power and generator power.
• Microsecond time-delay switching prevents power crossover and arcing.
• Shore power pass-through remains available without energizing the relays.
• DC-coil relays help prevent AC chatter noise and drop-out in low-voltage conditions.
• Flat-surface mounting allows the enclosure to be installed in multiple orientations while keeping the label readable.
• Internal layout provides access to the terminal bar and ground lugs for wiring connections.
• Wiring is divided into three sections for shore power, generator power, and output to the distribution panel or power center.
