QO1151021 - 15 Amp Circuit Breaker

QO1151021 - 15 Amp Circuit Breaker

If you need a 15 Amp Type QO circuit breaker with an integrated 120VAC shunt trip, the QO1151021 is built for applications where a circuit must be disconnected remotely while still providing reliable overcurrent protection. This single-pole plug-on breaker installs in compatible Type QO load centers and protects branch circuits against overloads and short circuits. The built-in shunt trip mechanism allows the breaker to open when an external 120VAC signal is applied, making it a practical choice for emergency shutdown systems, fire safety equipment, access control systems, and building automation. With a 10kA interrupting rating at 120VAC, it's well suited for many residential, commercial, and light industrial installations where dependable circuit protection and remote tripping are both required.
