Siemens HQR23B225L - 225 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens HQR23B225L is a high-capacity, 225A, 240V, 3-pole bolt-on molded case circuit breaker designed for robust branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for reliability in demanding electrical environments, this unit delivers precise protection where it matters most—right at the source of power distribution.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays solid even in installations with equipment-induced movement or harsh operating conditions.
• Thermal-magnetic trip unit combines thermal overload sensing with instantaneous magnetic response, delivering stable, repeatable protection performance across varying currents and loads.
• OEM-compatible design is engineered to pair with matching Siemens OEM load centers and panelboards, ensuring seamless integration and reliable electrical coordination.
• Versatile application suited for residential, commercial, and light industrial environments, making it a practical choice for upgrades, retrofits, or new installations.

Real-world use cases

• Upgrading main feeder protection in a residential or small commercial panelboard where a 225A, 240V 3-pole device is required for balanced, three-phase distribution.
• Retrofitting older electrical systems to improve short-circuit response and overload protection for critical equipment like commercial HVAC, pumps, or power distribution gear.
• Installing reliable branch-circuit protection in light industrial panels where vibration and equipment start-stop cycles are common.
