Siemens BQ2B035 - 35 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens BQ2B035 — a 35A, 240V, 2-pole bolt-on molded case circuit breaker from AmpState designed to protect your electrical system with precision and reliability. Built for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers, this breaker delivers consistent performance across residential, commercial, and light industrial applications.

Why this breaker stands out

• Rigid, vibration‑resistant mounting — bolt‑on mounting provides a secure bus connection that stays put even in environments with vibration, ensuring ongoing protection without loose connections.
• Thermal‑magnetic trip unit — delivers stable, repeatable protection, automatically responding to both overloads (heat) and short circuits (magnetic), so you’re covered for a wide range of fault conditions.
• Designed for OEM compatibility — compatible with matching Siemens OEM load centers and panelboards, facilitating straightforward integration into existing systems.
• Two‑pole 240V protection — simultaneously interrupts both hot legs, reducing shock risk and ensuring safe, coordinated disconnection for 240V circuits.
