Siemens QRH23B100L - 100 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens QRH23B100L is a 100 A, 240 V, 3‑pole bolt‑on molded case circuit breaker engineered to shield panelboards and load centers from overcurrent and short circuits. Built for reliability in demanding environments, this unit combines rugged mounting with precise protection, making it a dependable choice for commercial, residential, and light industrial electrical layouts.

Why this breaker stands out

• Secure bolt‑on mounting delivers a rigid, vibration‑resistant bus connection that stays tight through equipment start‑ups and ongoing operation, reducing the risk of loose connections and nuisance trips.
• Thermal‑magnetic trip unit ensures stable, repeatable protection by blending thermal overload sensing with instantaneous magnetic trip for short circuits—so you get predictable protection when it matters most.
• Three‑pole design supports balanced protection in 3‑phase systems, ideal for commercial equipment, motors, and lighting circuits that rely on solid phase separation.
• OEM compatibility paired with Siemens‑approved load centers and panelboards means straightforward installation and dependable performance without aftermarket fitment issues.
• Clear electrical ratings—100 A at 240 V—making it suitable for branch circuit protection in a wide range of panel configurations, from small business panels to light industrial setups.

Ideal use cases

• Three‑phase panelboards and load centers requiring robust branch circuit protection
• Upgrading existing Siemens or OEM‑matched panels where a bolt‑on, securely mounted breaker is preferred
• Applications in commercial spaces, light industrial environments, and residential settings with 3‑phase distribution
• Situations demanding reliable protection against both overload and short circuits with repeatable trip behavior
