SIEMENS QF130A Circuit Breaker 30A 1 Pole 120V AC 10kA

Siemens QF130A 30A GFCI Breaker

The Siemens QF130A is a single-pole miniature circuit breaker rated at 30 amps and 120 volts AC. It provides Class A ground-fault protection with a 5 milliampere trip threshold. The breaker features a 10 kiloampere interrupting rating and a plug-in mounting style for compatible Siemens load centres. It accepts copper wire from 14 to 10 AWG via lug terminals.

For Siemens Load Centre Protection

This breaker suits electricians and homeowners adding a 30-amp GFCI-protected circuit to a Siemens QF-series panel. It fits a single pole space and delivers ground-fault protection for personnel. Buyers needing a standard thermal-magnetic breaker without ground-fault function should look elsewhere. Installations requiring a two-pole or higher voltage device cannot use this single-pole 120-volt model.

10 kA Interrupting Rating Decides Fit

The 10 kiloampere AIR rating at 120 volts AC determines whether this breaker meets the available fault current at the installation point. Panels with higher available fault current require a breaker with a greater interrupting rating. Always verify the panel’s series rating and local code requirements before selecting this device.
