BQD2100 - 100Amp Circuit Breaker

BQD2100 - 100Amp Circuit Breaker

The Siemens BQD2100 is a 2-pole, 100-amp circuit breaker built to protect electrical circuits from overloads and short circuits in commercial and industrial settings. If you’re managing panelboards, lighting systems, or branch circuits, this breaker helps keep your equipment and wiring safe while allowing normal operation to continue without unnecessary interruptions.

Its thermal magnetic trip unit is straightforward and reliable—the thermal side handles long-term overloads, and the magnetic side reacts instantly to short circuits. The molded case design is compact but durable, and low-tab connections make installation quick and secure. Electricians, maintenance teams, and facility managers trust it for consistent performance, making it a solid choice for day-to-day operations.
