Siemens | HQR23B200L | Circuit Breaker | 200A | 3-Pole | 240V | 65kA

The Siemens HQR23B200L circuit breaker is engineered for dependable protection in demanding 240V, three‑phase systems. With a robust 200A rating and a high 65kA interrupting capacity, this unit is built to handle surge events and protect downstream equipment in commercial and industrial environments. Designed for maintenance, retrofit, and replacement projects, it offers a precise fit for compatible Siemens panels and distributions where exact specs matter.

• Amperage: 200 A
• Poles: 3‑Pole
• Voltage: 240V
• Interrupting Rating: 65 kA
• Part Number: HQR23B200L

Key advantages that matter in real-world installations:

• The part number is the best reference for compatibility, making it easier to match existing panels and feeders during retrofits or replacements.
• High protection margin: A 65kA interrupting rating provides strong protection for heavy inductive loads and fault conditions common in commercial and light industrial settings.
• Reliable performance under load: The 200A capacity supports sizable feeders and service sections without compromising trip reliability or nuisance tripping.
• Versatile use cases: Ideal for service entrances, main feeders, and subfeed protection in 3‑phase 240V distributions.
• Long-term value: Built to withstand daily cycling and fault events, helping extend panel life and reduce maintenance needs.

Who benefits most from this Siemens breaker?

• Facilities upgrading electrical distribution or replacing aging breakers in commercial buildings, manufacturing floors, or data centre peripheral infrastructure.
• Maintenance teams seeking a trusted, OEM‑matched component for retrofit projects that require exact specifications.
• Electrical contractors prioritizing clear compatibility references and reliable Siemens engineering in three‑phase 240V systems.

Practical tips for a smooth installation and reliable operation:

• Verify the fit by cross‑checking the exact panel model and conductor sizing with the HQR23B200L specifications before ordering.
• Ensure the system is de‑energized and the corresponding bus and lugs are compatible with a 3‑pole 240V configuration.
• Handle the breaker with appropriate torque and mounting procedures per standard electrical practices to maintain proper seating and protection performance.
• Keep a record of the part number (HQR23B200L) for future replacements and maintenance planning to ensure ongoing compatibility.

When you’re replacing or retrofitting, choose the Siemens HQR23B200L to align with your existing protection strategy, support robust fault handling, and maintain service continuity across your 3‑phase 240V equipment. Confirm fit and ratings before ordering to ensure a seamless upgrade or replacement.
