BQ3B015 - 15Amp Circuit Breaker

BQ3B015 - 15Amp Circuit Breaker

The Siemens BQ3B015 is a 15-amp, 3-pole circuit breaker designed for you to use in compatible Siemens Type BQ panelboards and electrical distribution equipment. Rated for 240 VAC, this breaker provides branch circuit protection for three-phase circuits and uses a common-trip mechanism that disconnects all three poles simultaneously when an overload or short circuit occurs. Its bolt-on design provides a secure connection within the panel, while the included load-side lugs help you simplify installation. With a 10 kAIC interrupting rating and UL 489 listing, the BQ3B015 is commonly used in commercial, industrial, and institutional electrical systems where 3-pole protection is required.
