GS1101B12UL
GS1101B12UL is a heavy duty manual transfer switch designed for reliable power transfer between utility and standby generator sources.
This 1-phase, 2-pole transfer switch is rated for 100 amps main and 100 amps standby at 120/240 volts AC.

The switch is housed in a NEMA 3R zinc-coated steel enclosure with a powder coat finish, suitable for outdoor surface mounting. It includes a 1-1/4 inch hub and accepts copper or aluminum wiring, with a wire range from 12 AWG to 1/0 kcmil. The unit is UL and cUL listed, RoHS compliant, and meets Buy American Act and ARRA requirements. The door has padlock provisions for all ON-OFF-ON positions, and the interlock prevents door opening unless the switch is in the OFF position.
