Square D | FHL26040 | Circuit Breaker | 2-Pole

The Square D FHL26040 2-Pole Circuit Breaker is a genuine, exact-fit solution designed for maintenance, retrofit, and replacement projects within compatible Square D panels. When you need reliable arc protection and a seamless swap, this 2-pole unit delivers the consistency you expect from a trusted brand.

Why this 2-Pole matters — two energized conductors are interrupted simultaneously, making it ideal for protecting 240V circuits or any application requiring dual-pole disconnection. Built to match Square D engineering standards, it ensures predictable trip performance and a secure, snug fit in panels that list this part number as a match.

• Exact-match reference: Part number FHL26040 is your most reliable compatibility guide. Use it to confirm acceptance by your panel model and amp rating before ordering.
• Genuine Square D quality: Manufactured to maintain consistent performance with other Square D components, helping minimize nuisance trips and maintain system reliability.
• Ideal for upgrades and replacements: Quickly swap in a like-for-like unit during panel maintenance or when retrofitting circuits that require a two-pole protection strategy.

This part is specifically suited for systems that require a precise 2-Pole breaker in Square D installations. To ensure proper protection and electrical integrity, verify panel compatibility by cross-referencing your panel model with the FHL26040 designation and confirm the appropriate ampere rating for your circuit.

Practical tips for best results: - Always shut off main power and test for voltage before beginning any breaker work. - Cross-check the panel label and service manual to confirm that FHL26040 is listed as an acceptable replacement. - If you’re upgrading from a single-pole arrangement, consult a qualified electrician to evaluate if a two-pole solution is required for the circuit. - Store spare breakers in a dry, cool location to preserve performance characteristics when you need a quick swap.
