Description

Built for heavy-duty commercial environments, this 45A molded case circuit breaker offers fixed thermal and magnetic trip functions to safeguard electrical systems. The unit mount design integrates seamlessly into Square D switchboards, control panels, and standalone enclosures. Although currently transitioning to the modern PowerPact B-Frame (BDL26045) architecture, this F-frame model provides essential HACR-rated performance, a 10kA interrupt capacity, and convenient visual trip indication.

What enclosures are compatible with the Square D FAL22045 circuit breaker?

The FAL22045 is designed for use in Square D FA Series enclosures, such as the FA100S (NEMA 1 surface mount), FA100X (NEMA 7 cast aluminum), and FA100AWK (NEMA 12/3R). It is also compatible with various Square D switchboards and industrial control panels that accept F-frame unit-mount breakers.

Is the Square D FAL22045 obsolete, and what is the direct replacement?

The direct cross-reference for the FAL22045 is the BDL26045, which is a 2-pole, 45A thermal-magnetic breaker with an upgraded 14kA interrupt rating at 600Y/347VAC.

What size wire does the FAL22045 accept, and what lugs are used?

This breaker comes standard with AL100FA lugs on both the line and load sides. These lugs accept copper or aluminum wire ranging from 14 AWG to 1/0 AWG.

Can the FAL22045 be used in DC applications?

Yes, in addition to its 240VAC rating, this breaker is rated for 250VDC systems, where it provides a 5kA interrupting capacity.

Does the FAL22045 feature a visual trip indicator?

Yes, this breaker features a standard over-center toggle mechanism. When a fault occurs, the handle moves to a center tripped position, providing clear visual indication that the breaker has operated.
