50 AMP Transfer Switch
120VAC-240VAC 50 AMPS/POLE70 AMP NEUTRAL
Automatic transfer switch
Automatically switches from power cord to generator
Heavy duty relay assembly will handle 50 amp power cord and up to 12kw generator
Transfers two hot poles and neutral simultaneously
Generator start up delay is provided to allow the generator to get up to speedUtilizes a micro switch on the neutral relay to ensure neutral lines are engaged before the hot lines
Designed with dc coiled relays to reduce hum, and terminal blocks to simplify wire connections
Quick and easy installation
Designed for oem and aftermarket applications
