CBB3090H - 90Amp Circuit Breaker

CBB3090H - 90Amp Circuit Breaker

The CBB3090H is a 90 amp, 3-pole bolt-on circuit breaker designed for use in commercial, industrial, and HVAC electrical systems. Built for three-phase applications, it helps protect circuits from overloads and short circuits while supporting the safe operation of connected equipment.

With a 10kA interrupting rating at 240VAC, this molded case circuit breaker is intended to interrupt fault currents before they can cause damage to wiring, motors, or other electrical components. The bolt-on mounting design provides a secure connection inside compatible panelboards, making it a common choice for power distribution equipment, motor circuits, and facility electrical systems.

The CBB3090H is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. Its 90-amp rating works well in a variety of installations where dependable three-phase circuit protection is needed. The compact design can also be helpful when working with limited panel space.

Whether you're replacing an existing breaker during maintenance, upgrading electrical equipment, or matching specifications for a new installation, the CBB3090H provides a practical solution for protecting three-phase circuits operating at 240VAC.
