UL 489

GFL Series (5A - 40A)
10kA UL489 Listed Branch Circuit Breaker with
Equipment Ground Fault Protection (RCBO)

UL489

The UL 489 Branch Circuit with Ground Fault Relay is the 1st in the industry! Since it includes a UL 489 Branch Circuit Protector, in many cases there is no need for upstream circuit protection. It comes in 1+N pole, 2 pole and 2 pole +N configurations at 240V AC, 120/240V AC. It has a rated current of 5 - 40A. It also has a Rated Short Circuit Interrupt Capacity of 10kA and comes in Overload tripping curves B, C and D. The Rated Frequency is 50/60Hz.
