CA2100X - 100Amp Circuit Breaker

CA2100X - 100 Amp Circuit Breaker

The CA2100X molded case circuit breaker is a 2-pole, 100 amp thermal-magnetic breaker designed for dependable overcurrent protection in 120/240VAC distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker is engineered to provide consistent branch circuit and feeder protection in commercial and industrial electrical panels. Rated at 10kA interrupting capacity at 120/240VAC, the CA2100X is suitable for applications requiring reliable short-circuit and overload protection within its specified ratings. Designed for operation in environments up to 40°C, this breaker includes load-side lugs for secure conductor termination and straightforward installation. If you’re maintaining or servicing existing electrical infrastructure, the CA2100X offers the correct form, fit, and function for compatible panel systems where this frame type is specified.
