QHB330 - 30Amp Circuit Breaker

QHB330 - 30Amp Circuit Breaker

The QHB330 is a 30-amp, 2-pole bolt-on circuit breaker rated for your 120/240VAC applications with a 65kA interrupting capacity. It's used to protect branch circuits by interrupting power when an overload or short circuit occurs. The bolt-on design provides a secure attachment to compatible panelboards, making it a common choice for your commercial and industrial electrical systems that require a high interrupting rating. This breaker is often selected when replacing an existing Type QHB breaker or servicing equipment that requires the same electrical ratings. Before installation, verify that the breaker type and ratings match the panel and application.
