CBB3100H - 100Amp Circuit Breaker

CBB3100H - 100Amp Circuit Breaker

The CBB3100H is a 100 amp, 3-pole bolt-on circuit breaker used in commercial, industrial, and HVAC electrical systems that require three-phase circuit protection. It helps protect wiring and connected equipment from overloads and short circuits, making it an important part of keeping electrical systems operating safely.

Rated for 10kAIC at 240VAC, this molded case circuit breaker is designed to interrupt fault currents before they can cause damage to electrical components. The bolt-on mounting style provides a secure connection inside compatible panelboards, which is why this type of breaker is commonly found in distribution equipment, motor circuits, and building electrical systems.

The CBB3100H is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. Its 100-amp rating makes it a practical choice for a variety of three-phase loads, while the compact design helps conserve valuable panel space.

Whether you're replacing an existing breaker during routine maintenance or matching specifications for a new installation, the CBB3100H provides a straightforward solution for protecting three-phase circuits operating at 240VAC.
