C340 - 40Amp Circuit Breaker

C340 - 40Amp Circuit Breaker

The C340 is a 40 Amp, 3-pole circuit breaker used in 240VAC three-phase electrical systems. It is designed to provide overcurrent protection for your branch circuits and features a common trip mechanism that opens all three poles simultaneously if an overload or fault condition occurs. This type of breaker is commonly used on three-phase equipment where all phases need to disconnect together.

Its plug-on design allows it to install into compatible panelboards without altering the existing panel layout. A 40 Amp breaker is often found protecting your HVAC equipment, refrigeration systems, pumps, compressors, motor loads, and other three-phase electrical equipment used in commercial and industrial facilities.

The C340 has a 10kA interrupting rating at 240VAC and is HACR rated for approved heating, air conditioning, and refrigeration applications. During maintenance, panel upgrades, or breaker replacement projects, matching the breaker's amperage, pole count, voltage rating, and mounting style is important to maintaining compatibility with the existing electrical system.
