Siemens AG NSBQE120 Miniature Circuit Breaker

Siemens QE120 GFEP Miniature Circuit Breaker is a 1-pole, 120 V AC, 20 A plug-on breaker that delivers both overcurrent protection and Ground Fault Equipment Protection (GFEP) for branch circuits. It is designed for use in Siemens panels and load centers that accept QE-type breakers, and it carries a 10 kA interrupt rating at 120 V, enabling prompt disconnection during fault conditions to help protect people and equipment. As part of the QE family, this 1-pole device protects a single hot conductor in residential or light commercial installations where ground-fault protection for receptacles or equipment is required. Its compact form factor simplifies substitution in compatible Siemens gear, and the 20 A rating makes it suitable for common circuits such as lighting and general outlets while providing integrated GFEP functionality for enhanced safety in appropriate installations.
