Square D | QDL22090 | Circuit Breaker | 90A | 2-Pole | 240V | 25kA

Meet the Square D QDL22090 circuit breaker — a purpose-built protection device engineered for reliability in 240V applications. With a 90 A rating and two poles, this breaker ensures two hot legs are simultaneously protected, making it ideal for 240V circuits in both retrofit projects and panel replacements. The 25kA interrupting capacity adds a robust safety margin, helping to quickly isolate faults and minimize damage to equipment and wiring.

• Amperage: 90 A
• Poles: 2-Pole
• Voltage: 240 V
• Interrupting rating: 25 kA
• Series: QDL family
• Usage: Maintenance, retrofit, and replacement in compatible Square D panels
• Compatibility note: Confirm fit and ratings before ordering; the part number QDL22090 is the best reference for compatibility

The QDL22090 is purposefully chosen when you need precise matching to existing Square D installations. It’s especially well-suited for upgrading older panels or refreshing a faulty breaker in a 240V circuit where both hot legs must trip together. By sticking to the QDL22090 part number as your compatibility reference, you minimize the guesswork and ensure a seamless fit with your panel’s labeling and internal bus connections.

Why choose this Square D circuit breaker over alternatives? It delivers reliable overcurrent protection with a clearly defined amperage and a strong interrupting capacity, reducing the risk of nuisance trips while maintaining swift fault isolation. This makes it a trustworthy choice for electrical systems that demand clear protection boundaries and dependable performance under fault conditions.

Who benefits most from the QDL22090? electricians, facility managers, and maintenance staff responsible for service panels that require exact QDL-series components. It’s a practical, standards-aligned option for replacement or retrofit projects where time, accuracy, and safety matter most.

Practical tip: keep the exact part number on hand during planning and purchasing to avoid compatibility issues. When installing, follow standard electrical safety practices and consult your panel’s labeling to confirm that the QDL22090 is the correct fit for the specific 240V, 2-pole circuit you’re protecting.
