Siemens | QJ22B100HL | Circuit Breaker | 100A | 2-Pole | 240V | Bolt-On

Engineered for Siemens panels that require a bolt‑on protection solution, the QJ22B100HL is a genuine Siemens circuit breaker delivering reliable overcurrent protection at a 100A rating with two poles in a 240V system. This unit is built to meet the exacting standards of Siemens equipment, ensuring consistent performance within compatible electrical panels.

This breaker is ideal for maintenance, retrofit, and replacement projects where matching specifications is critical. Reference the part number QJ22B100HL as your primary compatibility guide, and always confirm fit and ratings before ordering to avoid mismatches in panel design or trip characteristics.

Key specifications

• Amperage: 100A
• Pole configuration: 2-Pole
• Voltage rating: 240V
• Mounting type: Bolt-On
• Part number: QJ22B100HL

Why this matters

Choosing a genuine Siemens bolt-on circuit breaker like the QJ22B100HL ensures proper mechanical fit and electrical characteristics that align with your panel’s design. The bolt-on mounting provides a secure, vibration‑resistant connection in compatible Siemens enclosures, which helps maintain consistent protection for high‑demand circuits. By sticking to the exact part number, you minimize the risk of incompatibility that can arise with aftermarket substitutes and ensure your protection device behaves as intended under fault conditions.

Ideal use cases

• Replacing a blown or worn 100A two-pole breaker in Siemens bolt-on panels
• Retrofits in panels that require a precise QJ series, 2-pole, 240V solution
• Upgrading or maintaining service panels and subpanels that rely on a 100A feed

Installation and compatibility tips

Before ordering, verify that your panel accepts bolt-on breakers of the QJ series and that the QJ22B100HL matches your required amperage, pole count, and voltage. Always follow local electrical codes and use proper lockout/tagout procedures. Because installation and safe operation depend on panel design and wiring configurations, this work is best performed by a licensed electrician who can confirm fit, mounting, and trip coordination with the rest of the protection scheme.
