Siemens | QJ22B080 | Circuit Breaker | 2-Pole | 240V | Bolt-On

Meet the Siemens QJ22B080, a dedicated 2-pole circuit breaker built for reliable 240V protection in professional electrical panels. Designed for maintenance, retrofit, and replacement tasks, this bolt-on unit delivers a secure, long-lasting connection that keeps your system protected and compliant.

• Exact model fit — QJ22B080 is the precise reference for compatibility with Siemens panels. Always confirm fit and ratings before ordering to ensure seamless installation.
• Two-pole protection — provides coordinated disconnection for both conductors on 240V circuits, enhancing safety and reducing the risk of arc fault or electrical imbalance.
• Bolt-On mounting — a robust, field-ready mounting method that resists vibration and loosening, ideal for demanding environments and easier serviceability.
• Trusted Siemens engineering — built to meet stringent electrical standards, helping maintain panel integrity and system reliability over time.

Uses and practical scenarios:

• Retrofitting aging panels where a direct Siemens replacement is required to maintain the original protection scheme.
• Preparing spare breakers for facilities with 240V circuits, enabling quick replacements and minimizing downtime after trips or faults.
• Maintaining critical equipment in industrial or commercial settings where consistent, predictable trip characteristics matter for safety and uptime.

How to choose and install with confidence:

• Always verify the fit and ratings against your panel's specifications and the device’s electrical requirements.
• Remember this unit is 2-pole, 240V, bolt-on—ensure your enclosure supports bolt-on mounting and the panel configuration aligns with this setup.
• For a cohesive protection strategy, consider pairing this breaker with other Siemens QJ-series components to maintain consistent performance characteristics.
