BQ3B025 - 25Amp Circuit Breaker

BQ3B025 - 25Amp Circuit Breaker

Meet the Siemens BQ3B025, a 25 amp, 3-pole circuit breaker built to protect your three-phase electrical circuits. Designed for use in commercial and industrial panelboards, this breaker ensures that all three poles disconnect at the same time during overloads or short circuits, keeping your systems safe and stable. Rated for 240VAC and 10kA interrupting capacity, it’s a reliable choice for branch circuit protection where standard safety is needed. The bolt-on mounting style keeps installation secure, and load-side lugs simplify wiring, making it an easy fit for maintenance, upgrades, or replacements. Built for form, fit, and function, the BQ3B025 works with Siemens Type BQ equipment, providing consistent protection for motor loads, control panels, HVAC systems, and other 240V three-phase circuits.
