Siemens HQR23B225H 225A 240V 3-Pole Bolt-On Circuit Breaker

Introducing the Siemens HQR23B225H — a robust 225 A, 240 V, 3‑pole bolt‑on molded case circuit breaker engineered to safeguard your electrical system from overcurrent and short circuits. Built for dependable operation in panelboards and loadcenters, this unit delivers consistent protection in residential, commercial, and light industrial environments.

Why this breaker stands out

• Secure bolt‑on mounting provides a rigid, vibration‑resistant bus connection, helping maintain steady electrical contact even in dynamic or high‑load installations.
• Thermal‑magnetic trip unit delivers stable, repeatable protection — the thermal element handles prolonged overloads while the magnetic element responds instantly to severe short‑circuit conditions.
• OEM‑level compatibility designed to fit with matching Siemens OEM load centers and panelboards, ensuring coordinated protection and reliable integration into your existing systems.
• Three‑pole, 225 A at 240 V configuration is ideal for three‑phase circuits and heavy‑duty applications, providing comprehensive protection for larger branch circuits.
