CBB2090 - 90Amp Circuit Breaker

CBB2090 - 90Amp Circuit Breaker

The CBB2090 is a 90 amp, 2-pole bolt-on molded case circuit breaker for use in 120/240VAC electrical systems. Its purpose is straightforward: when a circuit sees an overload or short circuit, the breaker trips and shuts off power to help protect wiring and connected equipment.

A breaker in this size is often used on larger electrical loads. You'll commonly find 90 amp 2-pole breakers serving HVAC equipment, air conditioning condensers, refrigeration systems, compressors, subpanels, and motor-driven equipment. Because it protects both legs of a 120/240VAC circuit, it's a common sight in commercial buildings, warehouses, schools, office spaces, apartment properties, and light industrial facilities.

The bolt-on design allows the breaker to be secured in compatible panelboards, which is why it's frequently used in both replacement work and new installations. The CBB2090 carries a 10kA interrupting rating at 120/240VAC and is HACR rated for heating, air conditioning, and refrigeration applications. Its compact footprint can also be helpful when working in existing equipment where panel space is already spoken for.

If you're replacing a breaker and need a 90 amp, 2-pole bolt-on circuit breaker, this model is built for the job without unnecessary extras or complications. It does what a circuit breaker is supposed to do—protect the circuit and help keep equipment operating as intended.
