CBB3030H - 30Amp Circuit Breaker

CBB3030H - 30Amp Circuit Breaker

The CBB3030H is a 30 amp, 3-pole bolt-on molded case circuit breaker used in 240VAC three-phase electrical systems. When an overload or short circuit occurs, the breaker trips and disconnects power to help protect wiring, equipment, and connected loads.

A 30 amp 3-pole breaker is commonly found on circuits serving HVAC equipment, pumps, compressors, refrigeration systems, motor control circuits, and other three-phase machinery. Because all three poles operate together, the breaker protects the entire circuit rather than an individual phase. That's one reason this type of breaker is widely used in commercial buildings, warehouses, schools, manufacturing facilities, and other environments that rely on three-phase power.

The bolt-on mounting design allows the breaker to be securely installed in compatible panelboards, making it a common choice for both replacement work and new installations. The CBB3030H carries a 10kA interrupting rating at 240VAC and is HACR rated, allowing it to be used in many heating, air-conditioning, and refrigeration applications. Its compact footprint can also be helpful when working in existing equipment where available panel space is limited.

Whether you're replacing a breaker during routine maintenance or matching specifications for a project, the CBB3030H is a straightforward option when a 30 amp, 3-pole bolt-on circuit breaker is required.
