Product FAQs
7 answersWhat is the recommended replacement for the legacy FAL24090 circuit breaker?
Schneider Electric designates the PowerPact B-frame series as the direct replacement for legacy F-frame breakers. For a 90A, 2-pole application, the BDL26090 is the recommended substitute, though retrofitting may require updated mounting hardware.
Are the lugs on the FAL24090 removable, and what wire sizes do they accept?
Yes, the breaker uses removable mechanical lugs (catalog number AL100FA). These lugs accept 14 to 1/0 AWG copper or 12 to 1/0 AWG aluminum conductors.
Can I field-install a shunt trip on this F-frame breaker?
Internal accessories like shunt trips or auxiliary switches for the FAL series are typically factory-installed (often indicated by a four-digit suffix like 1021). If you require field-installable accessories, you may need to upgrade to a modern PowerPact breaker.
How is the FAL24090 mounted in an electrical system?
This is a unit-mount, feed-thru breaker. It is secured with mounting screws and requires wire connections at both the line and load terminals. It is not compatible with I-Line plug-on panelboards.
Does the FAL24090 support direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific DC control panels and battery applications.
What enclosures are compatible with the FAL24090?
This breaker is designed for standard Square D enclosures, industrial control panels, and switchboards configured for unit-mount F-frame breakers.
Can the trip settings on the FAL24090 be adjusted?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory set and cannot be modified in the field.
