Siemens | BQD6135 | Circuit Breaker | 35A | 1-Pole | 347V

Siemens BQD6135 is a purpose-built circuit breaker designed for reliable overcurrent protection in commercial and industrial electrical systems. This 35A, 1-pole device carries a 347V rating, making it a precise fit for 347V distribution networks where single-pole protection is required. Use it for maintenance, retrofit, or replacement projects where exact specifications matter — and the part number is your best reference for compatibility.

• Amperage: 35A
• Poles: 1-Pole
• Voltage rating: 347V
• Part number: BQD6135
• Brand: Siemens

Why this breaker stands out in the field

• Direct fit for compatible Siemens panels: Designed to work with Siemens distribution systems that accept BQD-series breakers, ensuring a dependable fit and predictable performance.
• Precise replacement option: The BQD6135 is the go-to reference when restoring original protection levels in existing installations, minimizing guesswork during retrofit or repairs.
• Targeted use in 347V environments: The 347V rating aligns with common commercial lighting and distribution schemes, providing appropriate protection without oversizing conductors or trip thresholds.

Ideal use scenarios

• Retrofits and panel upgrades where old or failed single-pole breakers need exact 35A protection
• Maintenance replacements in Siemens-compatible panels that operate on 347V systems
• New installations requiring a confirmed 1-pole, 35A protective device within 347V distribution networks

Installation and compatibility guidance

• Always confirm fit and ratings before ordering — the part number is the best reference for compatibility.
• Ensure your enclosure or panel accepts BQD-series breakers and that 347V service matches the intended circuit.
• Have a qualified electrician perform installation to maintain system safety and compliance.

Practical tips for optimal performance

• Archive the BQD6135 alongside related BQD-series breakers in your spare parts kit for faster replacements during preventive maintenance.
• When replacing, check the corresponding load characteristics of the protected circuit to ensure the 35A rating is appropriate for ongoing demand.
• If your system experiences frequent nuisance trips, re-evaluate circuit loads, conductor sizing, and any upstream protection to prevent unnecessary interruptions.
