southwire surge guard rv power protection with RVC automatic transfer switch - Model 40450

Surge Guard* 50A – Model 40450-RVC

Automatic Transfer Switch with Shore Power Sensing

RVC Compatible with Full RV Power Protection
120/240V, 50A, 60 Hz, 3350 Joules
  • Transfers to generator power automatically when energized after 30 second delay (generator mode). When both shore and generator power are available, generator dominates after a 30 second delay. Once generator shuts down, shore power activates after 3 second delay.
  • Total electrical protection from faulty park power
  • Provides protection against:
    • Power surges
    • Open ground
    • Open neutral
    • Low (<102V) and high (>132V) voltage
    • Reverse polarity
    • Miswired pedestal
    • High and low frequency
  • Multi-mode surge suppression
  • RVC communications allows instant display of voltage, current, and fault conditions on an RVC compatible device
    • RVC network communication of both generator and shore power availability through exclusive shore power sensing technology
    • Allows the RVC network to better control the power source of the RV and reconnect with shore power when it is available
  • Indicator lights on front of ATS indicate presence of input power for L1 and L2
  • Optional remote power monitor LCD Display (Part number 40299 sold separately)
    • Voltage and current (continuously monitored and indicated)
    • Easy to navigate faults in plain English
  • 65A, FLA mechanical interlocking contactors
  • UL approved – UL1008 full transfer switch rating
  • UL/CUL listed
