Description
Built for industrial applications, the Square D FAL34025 is a 25A, 3-pole molded case circuit breaker. This legacy F-Frame unit utilizes fixed thermal-magnetic elements to safeguard electrical systems. With a unit mount design, it installs into Square D enclosures, switchboards, and motor control centers. It is replaced by the newer HDL34025 frame. Delivering 18kAIC at 480VAC, it includes long-time and instantaneous trip functions. The breaker is HACR rated with a visual trip indicator.Specifications

Product FAQs
7 answersIs the Square D FAL34025 circuit breaker obsolete?
Yes, the legacy F-frame circuit breakers, including the FAL34025, are obsolete and have been superseded by the PowerPact B-frame series. However, direct replacements are often still sourced to maintain existing equipment without requiring panel modifications.
Can I install the FAL34025 in an I-Line panelboard?
No. The FAL34025 is a unit-mount, feed-thru circuit breaker designed for standard Square D enclosures, switchboards, and motor control centers. For I-Line plug-on panelboards, an FA frame breaker is required.
What is the difference between the FAL and FA circuit breakers?
The primary difference is the mounting style. FAL breakers are unit-mount with lugs on both the line and load sides, designed for individual enclosures or base mounting. FA breakers are designed with I-Line plug-on jaws on the line side for use in Square D I-Line panelboards.
What replacement lugs are compatible with the FAL34025?
The standard mechanical lug kit for the FAL34025 is part number AL50FA. These lugs accept 14-4 AWG copper or 12-4 AWG aluminum conductors.
Can the FAL34025 be used in DC electrical systems?
Yes, this breaker is rated for DC applications up to 250VDC with an interrupting capacity of 10kAIC. Ensure proper wiring configurations per Square D guidelines when applying molded case circuit breakers in DC circuits.
Are the thermal and magnetic trip settings adjustable on the FAL34025?
No, the FAL34025 features a fixed thermal and fixed magnetic trip unit. It provides long-time and instantaneous protection, but the trip thresholds cannot be field-adjusted.
Does the FAL34025 include a push-to-trip feature?
Yes, this breaker features a push-to-trip button on the front face. This allows electricians to manually trip the breaker to verify the mechanical operation of the tripping mechanism during routine maintenance.
