Siemens BQD6215 15A 2-Pole 347 V Circuit Breaker

Meet the Siemens BQD6215, a purpose-built 15 A, 2-pole circuit breaker designed for 347 V distribution in commercial and light industrial settings. Part Number BQD6215, this compact safeguard helps keep critical circuits from overload while ensuring safe, simultaneous disconnection of both live conductors.

Why this 2-pole breaker matters

In 347 V systems, protecting multi-wire circuits and maintaining phase balance are essential. The BQD6215 delivers reliable overcurrent protection, so when a fault arises, both poles trip together, preventing dangerous arc faults and minimizing downtime.

Key specifications

• Current rating: 15 A
• Poles: 2
• Voltage rating: 347 V
• Part number: BQD6215
• Manufacturer: Siemens

Who should use it

Ideal for commercial buildings and facilities running 347 V distribution networks, where circuits require stable, predictable protection for lighting, receptacle, or small equipment runs. If your panel is Siemens-compatible and you need a dependable 2-pole solution, the BQD6215 is a precise fit.

Use cases and practical applications

• Upgrading or replacing a failed breaker on 347 V circuits in office complexes, shopping centers, or industrial spaces.
• Installing new branch circuits that require 15 A protection in 347 V distribution networks.
• Maintaining consistent protection across multi-wire branch circuits where simultaneous trip is critical.

Installation and compatibility tips

Confirm that your electrical panel accepts Siemens BQD-series breakers. Always follow your panel manufacturer’s installation guidelines, and verify wiring configuration, bus compatibility, and secure mounting in the appropriate slot. For ongoing reliability, replace any breaker that shows signs of wear or frequent tripping with an exact BQD breaker model to preserve system integrity.
