Siemens HQR22B150HL 150A 2-Pole 240 V Circuit Breaker

Meet the Siemens HQR22B150HL—a rugged, high-capacity 2-pole circuit breaker designed for demanding 240 V applications. With a sturdy 150 A rating, this Siemens device delivers reliable protection for heavy-load circuits while ensuring easy integration into compatible panels.

Designed to protect both hot legs in a 240 V system, the HQR22B150HL provides quick, coordinated interruption during overloads or short circuits. Its 2-pole configuration ensures that both conductors are simultaneously disconnected, reducing the risk of dangerous arcing and helping keep downstream equipment safe.

Why choose the Siemens HQR22B150HL over generic alternatives? This model is built to fit Siemens panels that accept the HQR series, so you benefit from a precise fit, consistent performance, and dependable trip response that aligns with industry standards. The part number HQR22B150HL identifies a model engineered for durability and long-term reliability in both residential and light commercial settings.

Key benefits and practical advantages

• High-current protection at 150 A, ideal for feeders and heavy-load branch circuits such as large appliances, HVAC equipment, and subpanel feeders.
• 2-pole 240 V design protects both hot legs simultaneously, reducing voltage imbalances and electrical hazards.
• Siemens compatibility ensures a reliable fit in Siemens panels that accept HQR breakers, streamlining replacement and maintenance.
