Siemens BQD6335 35A 3-Pole 347 V Circuit Breaker

Siemens BQD6335 is a 35A, 3-pole circuit breaker designed for 347 V three-phase systems. With part number BQD6335, this unit delivers reliable protection for medium-load feeders in commercial electrical installations, aligning perfectly with Siemens panel architectures.

• Three-pole protection: Ensures simultaneous disconnection of all three phases during a fault, enhancing safety and reducing arcing across the distribution network.
• 347 V voltage rating: Built to support common 3-phase commercial power schemes, protecting circuits feeding lighting, motors, and other balanced loads at this voltage level.
• 35 A current rating: Provides appropriate overcurrent protection for moderate feeders while allowing normal operation of equipment like small motors and HVAC components.
• Direct compatibility: Engineered to integrate smoothly with Siemens BQD-series panels and replacement parts, simplifying installation and maintenance in existing systems.

Who this is for

• Facility managers and electricians protecting 3-phase feeders in commercial buildings that operate at 347 V.
• Electrical contractors stocking standardized breakers for quick field replacements in Siemens panel environments.
• Maintenance teams replacing aging or worn breakers on Siemens-compatible distribution boards.

Practical considerations and use cases

Ideal for safeguarding lighting feeders, rooftop HVAC drives, and small to mid-size motors connected to 347 V three-phase circuits. The 3-pole design helps maintain system stability by tripping all phases together, which is crucial for preventing phase-to-phase faults and protecting downstream equipment.
