Siemens BQ2B07000S01 - 70 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BQ2B07000S01 is a 70A, 240V, two-pole bolt-on molded case circuit breaker engineered for dependable branch-circuit protection in panelboards and load centers. Designed to withstand the demands of residential, commercial, and light industrial environments, this breaker delivers precise protection where it matters most.

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection that stays tight even in busy electrical panels, reducing movement and wear over time.
• Thermal-magnetic trip unit provides stable, repeatable protection performance—responding to overload with a governed thermal trip and to short circuits with an instantaneous magnetic trip for fast, reliable shutoff.
• OEM-compatible design is built to match Siemens load centers and panelboards, making replacements straightforward and ensuring consistent electrical characteristics across your panel.
• Two-pole, 70A at 240V configuration flips the switch on 240V circuits, protecting both conductors in shared neutrals and enabling safer, more efficient distribution for typical 240V loads.
• Molded case construction combines durability with compact form factor, ideal for densely packed panelboards where space and reliability matter.

This breaker helps solve everyday electrical challenges: preventing nuisance trips caused by vibration or loose connections, safeguarding against damaging short circuits, and simplifying panel maintenance with a consistent, predictable protection profile. It’s an excellent choice for upgrading existing Siemens panels or integrating into new installations where a robust bolt-on solution is required.

Ideal use cases include main or feeder protection in residential service panels, commercial distribution boards, and light industrial panels where 240V circuits demand reliable overcurrent and short-circuit protection.
