Key specifications at a glance

• Amperage: 40A
• Poles: 2-Pole
• Voltage: 240V
• Reference: Part number FAP22040

Why this Square D breaker stands out

• Exact-spec compatibility: Use the part number FAP22040 as the primary reference to confirm fit with your Square D panel. This minimizes mismatches in amperage, pole count, or voltage and speeds up installation.
• Dual-pole safety: The 2-pole design simultaneously disconnects both live conductors, reducing shock risk and maintaining balanced loads for safer, more predictable operation.
• Dedicated 240V protection: Specifically suited for high-demand 240V circuits in residential garages, workshops, or utility spaces where reliable 40A protection is required.
• Maintenance-friendly replacement: A straightforward option when upgrading or replacing aging breakers in compatible Square D panels, helping you restore protection quickly without panel rewiring.
• Durability you can trust: Engineered to meet standard electrical safety requirements, delivering consistent trip performance in everyday applications.

Use cases and who benefits most

• Home workshops powering 240V equipment such as welders, air compressors, or large power tools that require controlled current protection.
• Retrofits or panel upgrades where 40A, 2-pole, 240V protection is the correct specification for existing circuits.
• Maintenance intervals where replacing aging breakers with a precise, in-spec alternative keeps the electrical system compliant and safer.

How to verify compatibility (quick checklist)

• Confirm the panel accepts Square D FAP-series breakers and that a 2-pole, 240V configuration is appropriate for the circuit you’re protecting.
• Match the amperage rating (40A), pole count (2-Pole), and voltage (240V) to your panel’s labeling and the FAP22040 reference.
• Always cross-check the exact part number to ensure replacement accuracy and minimize downtime.

Note: Before purchasing, confirm fit and ratings against your panel’s specifications. The FAP22040 part number is your best reference for compatibility, making it the safest choice for maintenance, retrofit, or replacement projects.
