Siemens | HQJ3B225H00S11 | Circuit Breaker | 225A | 3-Pole | 240V | Bolt-On

Siemens HQJ3B225H00S11 represents robust, three‑phase protection for demanding electrical systems. This 225 A, 3‑pole, 240 V bolt‑on circuit breaker is built for maintenance, retrofit, and replacement in compatible Siemens panels, delivering reliable overcurrent protection where high load and three‑phase distribution are a requirement.

Key specifications

• Amperage: 225 A
• Poles: 3‑Pole
• Voltage: 240 V
• Mounting: Bolt‑On
• Part number: HQJ3B225H00S11

What makes this breaker stand out

• Direct bolt‑on mounting provides a secure, vibration‑resistant connection to compatible panels, simplifying installation and reducing the risk of loose connections in demanding environments.
• High‑load three‑phase protection is ideal for commercial and light‑industrial electrical distributions where balanced protection across all phases is critical.
• Siemens heritage and compatibility — designed to align with Siemens panel systems, ensuring predictable performance and streamlined maintenance when used as a replacement or retrofit component.

Ideal use cases

• Maintenance on existing Siemens 3‑pole, 240 V circuits where a 225 A rating matches the load profile.
• Retrofit projects where upgrading to a higher amperage or more reliable protection is required in three‑phase systems.
• Replacement for failed or worn breakers in commercial/industrial distribution panels that accept bolt‑on configurations.

Compatibility & installation notes

Before ordering, verify that HQJ3B225H00S11 is the correct match for your panel by cross‑checking the panel’s model and the breaker's ratings.
