BQD6115 - 15Amp Circuit Breaker

BQD6115 - 15Amp Circuit Breaker

The Siemens BQD6115 is a 15 Amp, single-pole circuit breaker used in 347VAC panelboard systems. It's often found in commercial buildings, schools, healthcare facilities, and other properties where 347-volt lighting and branch circuits are part of the electrical distribution system.

Built with a thermal magnetic trip unit, the BQD6115 protects circuits from both overloads and short circuits. The thermal element responds when current remains above normal levels for an extended period, while the magnetic trip reacts quickly when a fault occurs. This combination has been a standard choice in power distribution equipment for years because it's reliable and easy to maintain.

If you're working on a 347V system and need a 15 Amp single-pole circuit breaker, the Siemens BQD6115 is a familiar choice for electricians, maintenance teams, and contractors who service commercial and institutional electrical equipment.
