Siemens BQ2B100H - 100 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BQ2B100H – 100 A, 240 V, 2-Pole Bolt-On Molded Case Circuit Breaker is built for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. This heavy-hitter pairs robust electrical protection with a mounting design that stands up to real-world vibration and service life demands.

• Secure bolt-on mounting: delivers a rigid, vibration-resistant bus connection, reducing looseness and ensuring consistent electrical performance in challenging environments.
• Thermal-magnetic trip unit: combines temperature-based and magnetic trip mechanisms for stable, repeatable protection across a wide range of fault conditions and operating temperatures.
• 2-pole, 100 A, 240 V: protects both conductors with a single device, simplifying wiring, coordination, and panel layout.
• OEM-compatible: designed for seamless compatibility with matching Siemens load centers and panelboards, making replacements and upgrades straightforward.
• Versatile for multiple applications: ideal for residential service panels, commercial distribution boards, and light industrial feeder protection.

Practical use scenarios include upgrading aging panels to modern, reliable overcurrent protection, retrofitting existing Siemens installations to meet current codes, or provisioning new build-outs where a sturdy bolt-on breaker is preferred. The 2-pole design ensures synchronized protection across both hot legs, enhancing safety and system reliability in everyday electrical layouts.
