Siemens | HQR22B100H | Circuit Breaker | 100A | 2-Pole | 240V

Siemens HQR22B100H is a 100-amp, 2-pole circuit breaker designed for 240-volt circuits in compatible panels. Built for maintenance, retrofit, and replacement projects, this device ensures you restore reliable protection with the exact specifications your panel requires.

• Amperage: 100 A
• Poles: 2-Pole
• Voltage: 240 V
• Part number: HQR22B100H
• Applications: suitable for maintenance, retrofit, and replacement where matching specs are required
• Compatibility note: Confirm fit and ratings before ordering; the part number is the best reference for compatibility

Why this specific Siemens breaker stands out: when your electrical panel calls for a 100A, 2-pole, 240V device, the HQR22B100H is intentionally matched to that design. Using the correct part number ensures the interruption ratings, seating, and connection geometry align with your panel’s engineering, helping maintain performance, safety, and code compliance during fault conditions.

Ideal use scenarios include panel maintenance and upgrades where a like-for-like replacement is required, or when retrofitting circuits that demand a robust 240V two-pole protection. If you’re rebuilding or extending a service, this breaker provides a reliable path to restore power safely while keeping the electrical system consistent with Siemens specifications.

Practical tips for installation and compatibility:

• Verify fit first: Use the exact part number HQR22B100H as your reference to ensure compatibility with your Siemens panel.
• Safety first: Power down the main before removing or installing a breaker, and test for zero voltage on the circuit.
• Documentation: Keep the panel labeling and this part number in maintenance records for future servicing.
