FJ63B125 - 125Amp Circuit Breaker Description
FJ63B125 - 125Amp Circuit Breaker
The FJ63B125 is a 125 Amp, 3-pole molded case circuit breaker used in electrical equipment that requires an FJ6 frame breaker. It's typically installed as a replacement when servicing existing switchboards, panelboards, or other power distribution equipment where the original breaker needs to be matched. With a thermal magnetic trip mechanism and a non-interchangeable trip unit, the FJ63B125 is intended to protect your circuits from overloads and short circuits while matching the characteristics of the original installation. The breaker includes load-side lug terminals and is rated for 50/60Hz operation in 40°C ambient conditions.
