Generac 9951 200 Amp Service Rated Automatic Transfer Switch with Integrated SPD

Generac’s 200 Amp single-phase service NEMA 3R rated automatic transfer switch is used for transferring electrical load from a utility (normal) power source to a generator (standby) power source.

This automatic transfer switch is used for transferring electrical load from a utility (normal) power source to a generator (standby) power source. Transfer of electrical loads occurs automatically when the utility power source has failed or is substantially reduced and the generator source voltage and frequency have reached an acceptable level. The transfer switch prevents electrical feedback between two different power sources (such as the utility and generator sources) and, for that reason, codes require it in all standby electric system installations. The transfer switch consists of a transfer mechanism, utility service disconnect circuit breaker, SPD device and fused control module with brownout protection
