QB2430-50 - 50 Amp Circuit Breaker

QB2430-50 - 50 Amp Circuit Breaker

When you need a replacement circuit breaker, getting the correct specifications is critical. The QB2430-50 is a 3-pole, 50-amp bolt-on circuit breaker built for compatible QB24 applications requiring a 240VAC rating and 10k A.I.C. rating. This breaker is commonly used in existing electrical systems where matching the original breaker configuration, mounting style, and electrical ratings is important.

The QB2430-50 provides the form, fit, and function required for compatible replacement applications. Its bolt-on design allows it to be installed in equipment built for this connection style, while the 3-pole configuration makes it appropriate for systems requiring three-phase circuit protection. Built to last, this circuit breaker is a practical choice for maintaining electrical panels and distribution equipment that rely on QB24 type breakers.
