Siemens BQD6235 - 35 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BQD6235 is a rugged 2-pole bolt-on molded case circuit breaker rated for 35 amps at up to 600 volts, built to safeguard branch circuits in panelboards and loadcenters with dependable overcurrent and short-circuit protection. Designed for residential, commercial, and light industrial applications, it delivers consistent protection where reliability matters most.

Key features that set this breaker apart:

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, minimizing micro-arcs and ensuring stable electrical performance in noisy or busy electrical environments.
• Thermal-magnetic trip unit combines a thermal element for gradual overload protection with a magnetic mechanism for rapid response to short circuits, delivering predictable, repeatable protection.
• 2-pole design reduces the risk of phase-to-phase faults and simplifies protection of multi-wire branch circuits.
• 600V rating supports higher voltage applications common in commercial and light industrial settings, expanding versatility beyond standard 120/240V panels.
• OEM-ready compatibility engineered to pair with matching Siemens loadcenters and panelboards, ensuring proper fit, electrical coordination, and streamlined serviceability.

What makes the BQD6235 particularly practical for real-world use:

• —ideal for feeders, HVAC equipment, lighting, and receptacle circuits where consistent trip behavior matters during fault conditions.
• with bolt-on mounting simplifies installation, removal, and field maintenance, reducing downtime during panel upgrades or replacements.
• —a molded case construction designed to withstand vibration and environmental stress in both new builds and retrofit projects.
• —when used in Siemens-panel environments, it maintains optimized coordination with upstream protection devices, helping to prevent nuisance trips and improve overall system reliability.
