C320 - 20Amp Circuit Breaker

C320 - 20Amp Circuit Breaker

The C320 is a 20 Amp, 3-pole circuit breaker used in 240VAC three-phase electrical systems. It provides overcurrent protection for your branch circuits and features a common trip design that opens all three poles at the same time when a fault occurs. This type of configuration is commonly used on three-phase equipment where all phases must disconnect together.

The plug-on mounting design allows the breaker to fit into compatible panels without changing the existing panel layout. A 20 Amp, 3-pole breaker is often used on motor circuits, HVAC equipment, refrigeration systems, pumps, compressors, control panels, and other equipment powered by three-phase electrical service.

The C320 is HACR rated for approved heating, air conditioning, and refrigeration applications and carries a 10kA interrupting capacity at 240VAC. In commercial and industrial facilities, breakers like the C320 are commonly replaced during panel maintenance, equipment upgrades, or electrical repairs. Matching the correct breaker type, amperage rating, and pole configuration helps you ensure compatibility with the existing electrical system.
