Siemens QF130AN NN Molded Case Circuit Breaker

Siemens QF130AN NN Molded Case Circuit Breaker is a 30 A, 240 V, single-pole unit designed with plug-on neutral GFCI protection. The QF130AN NN is a plug-on neutral variant of the QF130AN family, built for circuits that require ground-fault protection in Siemens panel installations. It measures roughly 3 in long by 1.1 in wide and uses a plug-in connection with plug-on mounting, enabling straightforward installation or replacement in compatible panels. This 1-pole breaker is rated for 30 A operation at 240 V AC, providing fast disconnection on ground faults to protect personnel and equipment on the protected circuit. As a molded-case breaker, it integrates into standard Siemens low-voltage distribution systems and is commonly stocked in electrical supply catalogs for adding GFCI protection to branch circuits that demand reliable overcurrent and ground-fault protection.
