QOB2150VH - 150Amp Circuit Breaker

QOB2150VH - 150Amp Circuit Breaker

When your electrical system demands dependable protection for higher-capacity circuits, the QOB2150 bolt-on circuit breaker is built to get the job done. Rated at 150 amps with a 2-pole configuration, this Type QOB-VH circuit breaker helps safeguard electrical equipment and branch circuits from overloads and short circuits in compatible 120/240VAC systems. Its 22kA interrupting capacity provides an added level of protection in applications where fault current ratings matter. The bolt-on design creates a secure connection to the panelboard, making it a popular choice for commercial and industrial electrical systems where long-term performance is essential. Because this breaker requires 8 panel spaces, it's designed for larger electrical loads that call for a higher amperage solution. Whether you're replacing an existing breaker during scheduled maintenance or upgrading an electrical distribution system, the QOB2150 offers the dependable protection professionals expect while helping keep your system operating safely and efficiently.
