CBB2100 - 100Amp Circuit Breaker

CBB2100 - 100Amp Circuit Breaker

The CBB2100 is a 100 amp, 2-pole bolt-on molded case circuit breaker used in 120/240VAC electrical systems. Its job is simple: if a circuit experiences an overload or short circuit, the breaker trips and shuts off power to help protect wiring and connected equipment.

The bolt-on mounting style allows the breaker to be securely fastened in compatible panelboards, making it a familiar choice for electricians, contractors, and maintenance personnel. The CBB2100 carries a 10kA interrupting rating at 120/240VAC and is HACR rated for heating, air conditioning, and refrigeration applications. Its compact size can also be useful when replacing an existing breaker in equipment where available panel space is limited.

Whether you're matching an existing specification, replacing a failed breaker, or maintaining a power distribution system, the CBB2100 is a straightforward option when a 100 amp, 2-pole bolt-on circuit breaker is required.
