CHB3100 - 100Amp Circuit Breaker

CHB3100 - 100 Amp Circuit Breaker

The CHB3100 circuit breaker is a 3-pole, 100 amp, bolt-on style breaker designed for use in CHB frame panelboards and distribution equipment operating at up to 240VAC. Built to provide dependable overcurrent and short-circuit protection, this breaker features a 10kA A.I.C. rating at 240VAC, making it suitable for a wide range of commercial and light industrial electrical systems. Its bolt-on mounting design ensures a secure mechanical and electrical connection to the panelboard bus, helping maintain system integrity in demanding applications. When you need a direct replacement that matches original form, fit, and function, the CHB3100 offers compatibility with existing CHB panel configurations while meeting essential electrical protection requirements. These breakers are built to last and engineered for consistent operation in legacy systems where proper coordination and rating compliance matter most.
