QB2430-100 - 100 Amp Circuit Breaker

QB2430-100 - 100 Amp Circuit Breaker

The QB2430-100 100 Amp circuit breaker is a straightforward solution for systems that use QB-frame bolt-on breakers. It’s made to handle normal electrical loads while stepping in when there’s an overload or short circuit. Installation is simple since it mounts directly into compatible panelboards, which helps cut down on downtime during replacements or service work. The breaker’s metal housing and clear factory markings also make it easier to work with during installs and inspections. It’s commonly used in residential panels, commercial spaces, and light industrial setups where consistent performance is expected.
