Square D | QJL22125 | Circuit Breaker | 2-Pole | 240V | Feed-Through

Square D QJL22125 Circuit Breaker — a precise 2-pole, 240V feed-through unit designed for reliable overcurrent protection in electrical panels. Built to withstand routine maintenance, retrofit, and replacement scenarios, it delivers an exact-match solution when your system requires identical specs.

Why this matters: in electrical work, matching the exact part number is the fastest path to safe, compliant operation. The QJL22125 is identified by its part number, making compatibility checks straightforward and minimizing downtime. This 2-pole configuration handles full 240V circuits, making it ideal for protecting downstream loads that rely on two hot conductors sharing a common neutral or ground reference in compatible panels.

Key advantages

• Precise 2-pole, 240V protection for high-demand circuits
• Feed-through design that simplifies wiring and downstream connections in compatible panels
• Part-number driven compatibility: QJL22125 as the best reference for replacement or retrofit
• Well-suited for maintenance, retrofit, and replacement projects where exact specs are required

Ideal use cases

• Replacing aging or failed 240V two-pole breakers in residential or light commercial panels
• Retrofit projects that demand an exact spec match to maintain panel layout and wiring schemes
• Maintenance programs aimed at preserving circuit protection without altering panel architecture

How to ensure a perfect fit — before you order, confirm the breaker’s fit and ratings in your panel. The part number QJL22125 is the most reliable reference for compatibility, ensuring you get the right device without guesswork.
