C330 - 30Amp Circuit Breaker

C330 - 30Amp Circuit Breaker

The C330 is a 30 Amp, 3-pole circuit breaker designed for use in 240VAC three-phase electrical systems. It provides branch circuit protection against overloads and short circuits and features a common trip design that disconnects all three poles at the same time when a fault occurs. This type of breaker is commonly used on equipment where all phases must be opened simultaneously to protect the circuit and connected equipment.

Its plug-on design allows it to fit into compatible panelboards without changing the existing panel layout. The 30 Amp rating is often found on motor circuits, HVAC equipment, pumps, compressors, refrigeration systems, and other three-phase electrical loads. In many facilities, breakers of this size are used on dedicated equipment circuits where consistent electrical protection is required during everyday operation.

Whether you're replacing an existing breaker or maintaining a three-phase distribution system, matching the correct amperage, pole configuration, and breaker type helps ensure compatibility with the equipment already installed.
