QO3501021 - 50A Circuit Breaker Description
QO3501021 - 50A Circuit Breaker
The QO3501021 is a 50 Amp, 3-pole QO plug-on circuit breaker equipped with a 120VAC shunt trip device for your applications where remote tripping is required. When a compatible control signal is applied, the shunt trip automatically opens the breaker, making it a practical option for emergency shutoff systems, fire alarm integration, and other control applications. Built for use in compatible QO load centers and panelboards, this breaker provides protection against overloads and short circuits while offering the convenience of plug-on installation. Its 10kA interrupting rating at 240VAC makes it suitable for many commercial and industrial electrical systems. Whether you're replacing a worn breaker during maintenance or installing one in a new panel, the QO3501021 delivers the combination of circuit protection and remote operation that many facilities depend on every day.
