With a 150A rating and a 2-pole configuration, this device safeguards both conductors in a circuit while delivering robust fault-current interruption up to 65kA. Built for maintenance, retrofit, and replacement projects, it’s a practical choice for demanding panels that require precise compatibility with Siemens’ HQR family.
Key specifications at a glance
- Amperage: 150A
- Poles: 2-Pole
- Voltage: 240V
- Interrupting rating: 65kA
Why choose the Siemens HQR22B150L
This 2-pole 150A breaker delivers dependable protection for high-load circuits, ensuring that both legs disconnect simultaneously during a fault. The 65kA interrupting capacity provides a strong margin against short-circuit events, helping to protect downstream equipment and wiring from damage. Its design aligns with Siemens’ HQR-series panels, facilitating smooth retrofits and replacements where exact part-number compatibility is essential.
Ideal use cases
- Panel replacements in service entrances or heavy-load distribution boards
- Retrofits to upgrade or reconfigure 240V circuits that require 150A protection
- Maintenance and part replacement in existing Siemens HQR31/32/ family installations where the HQR22B150L matches the required specs
Compatibility and installation notes
To ensure proper fit and safe operation, always confirm the panel’s compatibility with the HQR22B150L before ordering. The part number is the best reference for ensuring correct alignment with your Siemens equipment and existing wiring arrangements.
Practical tips for best results
- Before installation, power down the system and verify there are no live circuits in the panel.
- Have an electrical professional perform the replacement to maintain compliance with local codes and safety standards.
- Keep the original packaging until installation is complete, and record the exact part number for future maintenance.
