NBGF20 - 20Amp Circuit Breaker

NBGF20 - 20Amp Circuit Breaker

The NBGF20 20 amp circuit breaker is a single-pole, bolt-on breaker designed for 120V branch circuits in residential and light commercial panels. Rated at 10k A.I.C. at 120VAC, it helps stop overloads and short circuits before they can cause damage to wiring or connected equipment. It uses a thermal magnetic trip system, so it responds appropriately to both sustained overloads and sudden fault conditions. The bolt-on mounting style provides a solid, secure connection to the panelboard, which is especially important in applications where vibration or long-term use can loosen clip-in styles. If you’re replacing an existing breaker in a compatible NBGF frame panel, this model offers a straightforward fit without unnecessary adjustments. It’s a practical choice for keeping lighting, receptacle, and general-purpose circuits properly protected.
