QOB2201021 - 20Amp Circuit Breaker

QOB2201021 - 20Amp Circuit Breaker

The QOB2201021 is a 2-pole, 20-amp Type QOB bolt-on circuit breaker with an integrated 120VAC shunt trip device, giving you dependable circuit protection along with the ability to trip the breaker remotely when needed. It's commonly used in commercial and industrial electrical systems where remote shutdown is part of the safety design, such as fire alarm interfaces, emergency stop systems, or building automation controls. The bolt-on design creates a secure connection inside compatible panelboards, helping keep the breaker firmly in place over years of service. Rated for 10kA at 120/240VAC, the QOB2201021 helps protect branch circuits against overloads and short circuits while adding the convenience of remote operation through its built-in shunt trip. If you're replacing an existing breaker or maintaining electrical equipment, this model offers a practical solution for applications that require both reliable protection and remote disconnect capability.
