C290 - 90Amp Circuit Breaker Description
C290 - 90Amp Circuit Breaker
The C290 is a 90 Amp, 2-pole circuit breaker used in 120/240VAC electrical systems that require higher-capacity branch circuit protection. It features a common trip design, meaning both poles disconnect together if an overload or short circuit occurs. This type of breaker is commonly used on circuits where simultaneous disconnecting is required and maintaining compatibility with the existing panel is important.
The plug-on design allows the breaker to install into compatible load centers without altering the panel layout. With its 90 Amp rating, the C290 is often found protecting larger electrical loads such as HVAC equipment, electric furnaces, heat pumps, water heaters, subpanels, and other dedicated circuits that require a higher level of overcurrent protection.
Whether you're replacing an existing breaker during service work or maintaining an electrical distribution system, selecting the correct breaker type, amp rating, and pole configuration helps ensure proper fit and operation.
