Siemens | HQJ23B225H00S11 | Circuit Breaker | 225A | 3-Pole | 240V

Introducing the Siemens HQJ23B225H00S11 circuit breaker—a high‑current, three‑pole protection solution engineered for demanding 240V systems. With a 225A rating, this breaker is built to reliably interrupt and isolate heavy load circuits, delivering safe, decisive interruption when protection is required.

why this matters

When your electrical panel serves sizable feeders or equipment, you need a breaker you can trust. The HQJ23B225H00S11 offers three independent poles to reliably disconnect all conductors simultaneously, reducing the risk of arcing and improving safety during maintenance or fault conditions. Its 240V specification aligns with common three‑phase and single‑phase commercial and industrial applications, ensuring robust protection across a range of installations.

Key applications

• Maintenance and retrofit projects where existing equipment requires a high‑amperage, 3‑pole 240V protection device
• Replacement in commercial or industrial panels that call for Siemens‑class reliability and compatibility with HQJ series components
• Protection for sizeable feeders and heavy loads in electrical rooms, service entrances, and equipment rooms

core specifications

• Amperage: 225 A
• Poles: 3‑Pole
• Voltage: 240 V
• Reference part: HQJ23B225H00S11 — the best reference for compatibility checks

fit, compatibility, and installation mindset

Before ordering, verify that the panel or enclosure calling for HQJ23B225H00S11 matches the 225A, 3‑pole, 240V specifications. The part number is your most reliable compatibility guide, helping you avoid mismatches during retrofit or replacement projects. Always follow Siemens installation guidelines and your system’s maintenance procedures to ensure correct mounting, secure terminations, and proper clearing distances.

practical benefits and outcomes
