CBB2040 - 40Amp Circuit Breaker

CBB2040 - 40Amp Circuit Breaker

The CBB2040 is a 40 amp, 2-pole bolt-on molded case circuit breaker used in 120/240VAC electrical systems for branch circuit protection. When an overload or short circuit occurs, the breaker interrupts the flow of electricity to help protect your conductors, equipment, and connected loads from damage.

Its 2-pole configuration allows it to protect both legs of a 120/240VAC circuit, making it a common choice for larger electrical loads that require a 40 amp breaker. The bolt-on design provides a secure connection in compatible panelboards and distribution equipment, which is why this style of breaker is frequently found in commercial and industrial installations.

The CBB2040 carries a 10kA interrupting rating at 120/240VAC and is HACR rated for use in many heating, air conditioning, and refrigeration applications. It's often used for your HVAC equipment, refrigeration systems, lighting panels, control circuits, and other electrical distribution needs where a 40 amp, 2-pole circuit breaker is specified. Its compact size also makes it easier to work with when panel space is limited or when replacing an existing breaker.
