Siemens QRH23B200L - 200 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens QRH23B200L is a 200 A, 240 V, 3-pole bolt-on molded case circuit breaker built to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed for durability and long-term performance, this unit powers residential, commercial, and light industrial electrical pathways with confidence.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection. Tight, dependable fastening minimizes movement, reduces electrical noise, and helps maintain consistent protection even in environments with equipment vibration.
• Thermal-magnetic trip unit combines precise thermal overload sensing with instantaneous magnetic short-circuit protection. This dual-stage protection delivers stable, repeatable performance and fast clearing of fault conditions when they occur.
• OEM-compatible design is purpose-built to fit and operate with matching Siemens panelboards and loadcenters, streamlining replacements and upgrades without sacrificing fit or function.
• Versatile for diverse applications – well suited for new installations or service upgrades in homes, small commercial spaces, and light industrial setups that require robust, code-compliant protection.

The bolt-on design makes installation straightforward for technicians, while the thermal-magnetic protection curve helps align with standard electrical codes and field expectations for reliable operation over the life of the panel.

Ideal use cases

• Replacing an aging or undersized breaker in existing Siemens panelboards or loadcenters
• Upgrading service capacity in residential basements, garages, or multi-family units where 200 A main feeds branch circuits
• Commercial small-office or light-industrial panels requiring robust protection against both overloads and short circuits
• New installations where a proven, OEM-compatible bolt-on solution is prioritized for durability and compatibility

Practical tips for optimal performance

• Ensure torque on each bolt is tightened to the manufacturer’s specification to maintain a solid bus connection and consistent trip characteristics.
• Verify compatibility with your existing panelboard or loadcenter to ensure a seamless fit and coordinated protection strategy.
• Plan for service continuity by labeling circuits clearly and coordinating with downstream protection to avoid simultaneous de-energization of critical loads.
