QB50 - 50 Amp Circuit Breaker Description
QB50 - 50 Amp Circuit Breaker
The QB50 50 Amp Circuit Breaker is built for everyday electrical work where dependable protection matters. It’s designed to help protect circuits from overloads and short circuits and fits naturally into residential panels as well as many light commercial setups. The single-pole design supports standard 120 VAC applications, while the bolt-on mounting helps keep the breaker firmly in place once installed. Its smaller footprint also makes it easier to work with in tighter panels, especially during replacements or quick system upgrades.
