Siemens | QJ22B080L | Circuit Breaker | 80A | 2-Pole | 240V

Meet Siemens QJ22B080L, a robust circuit breaker designed for reliable overcurrent protection in Siemens QJ-series panels. With 80 amps of trip capacity across 2 poles at 240V, this unit is built for demanding branch circuits and service feeds.

Key specifications

• Amperage: 80A
• Poles: 2-Pole
• Voltage rating: 240V
• Part number: QJ22B080L

Why choose the Siemens QJ22B080L

Designed to integrate seamlessly with Siemens electrical panels that accept QJ-series breakers, this unit ensures a precise fit and consistent electrical performance. The 2-pole configuration provides simultaneous protection for multi-wire circuits, helping prevent dangerous imbalances and enhancing overall panel safety. The 240V rating aligns with common residential and commercial distribution needs, making it suitable for a range of installations from appliance feeders to small motor circuits.

Use cases and applications

• Retrofit or replacement in existing Siemens panels that specify QJ22B080L or QJ-series equivalents.
• Upgrade of branch circuits that require higher current protection (up to 80A) for equipment or receptacle circuits.
• New installations in environments using 240V multi-wire branch circuits that require reliable, code-compliant protection.

Fit and installation guidance

Before ordering, confirm fit and ratings on your panel labeling. The QJ22B080L part number is the best reference for compatibility with Siemens panels. If in doubt, cross-check the panel's catalog or contact the manufacturer to ensure the 80A, 2-pole, 240V configuration matches your circuit requirements.

Practical tips for optimal performance

• Handle with care and ensure the main power is shut off during replacement to avoid shock hazards.
• Keep spare breakers in the same model family (QJ-series) to simplify future maintenance.
• Verify that the connected load does not exceed the 80A rating to prevent nuisance tripping and protect the circuit.

Choosing the right breaker matters for safety and reliability. The Siemens QJ22B080L delivers targeted protection for your 2-pole, 240V circuits, backed by Siemens' engineering and compatibility with QJ-series panels. Add it to your system where exact fit and specification alignment is essential.
