50 amp Surge Guard Auto Transfer Switch Buy Today

This hardwired automatic transfer switch from Surge Guard/Southwire is designed for RV or mobile power systems at 120/240 volts and 50 amps. It seamlessly switches load from shore to generator power when needed, while providing built-in surge protection and fault-power monitoring in one unit

• Automatically transfers to generator power after about 30 seconds when it becomes available; when generator power stops, it reverts back to shore after approximately 3 seconds

• Rated for 50 amp full load (FLA) contactors, mechanical interlocking, and UL 1008 full-transfer-switch listing (UL/CUL listed) — making it a robust choice for large RV/marine installations
