Schneider Electric | FDA220451 | Circuit Breaker | 45A | 2-Pole | 240V

Schneider Electric FDA220451 Circuit Breaker is a precisely matched protective device designed for reliability in maintenance, retrofit, and replacement scenarios. With a 45A rating across 240V and a compact 2-pole design, this breaker protects both legs of a 240-volt circuit while delivering dependable overcurrent protection for a range of equipment and installations.

• Amperage: 45A
• Poles: 2-Pole
• Voltage: 240V

Why this part matters The FDA220451 is the exact Schneider Electric part reference you need when compatibility matters. Using the correct part number ensures the breaker fits your panel’s bus connections and maintains the intended protection characteristics, reducing the risk of misfit or premature trips. This is especially important in retrofit projects or when replacing an aging device where the specification sheet calls for a 45A, 2-pole, 240V solution from Schneider Electric.

Ideal use cases

• In-situ replacement for failed breakers in existing 240V circuits that require 45A capacity
• Retrofit projects upgrading protective devices to Schneider Electric standards
• Maintenance tasks where matching specifications are essential to system reliability

What makes it stand out Unlike generic substitutes, this FDA220451 breaker is built to align with Schneider Electric’s panel and accessory ecosystem. The two-pole design ensures simultaneous protection of both hot conductors on a 240V circuit, supporting balanced protection for motors, compressors, HVAC equipment, pumps, and other 240V loads. Its in-kind form factor minimizes installation downtime and preserves panel aesthetics and clearance.

Practical guidance for a confident purchase

• Always confirm fit and ratings before ordering by cross-referencing the part number FDA220451 with your panel model and equipment needs.
• Keep a spare FDA220451 on hand for faster maintenance or retrofit turns in facilities with frequent 240V circuit updates.
• When planning replacement, document the circuit’s load characteristics to ensure the 45A rating provides adequate protection without nuisance trips.

Whether you’re maintaining a commercial electrical system, upgrading an aging panel, or performing a precise retrofit, the Schneider Electric FDA220451 Circuit Breaker delivers the expected performance, reliability, and compatibility you rely on for safe, continuous operation of your 240V circuits.
