Industrial FAL34040 Three-Phase Circuit Breaker

Square D by Schneider Electric FAL34040 is a 3-pole, 40-amp molded-case circuit breaker (MCCB) designed for 480V AC three-phase systems. This Type FAL device uses thermal-magnetic trip protection and features line-to-load feed-through lugs (line + load) for straightforward panel connections. Rated for 480V, it provides 40A of circuit protection with an 18 kA interrupting capacity at 480V and a compact footprint measuring roughly 6.4 inches tall, 4.13 inches long, and 4.5 inches wide. The unit is UL and CSA listed, making it suitable for industrial power distribution panels and feeders in 3-phase 480V installations. The FAL34040 configuration (3P, 3PH) is commonly used where space is limited but reliable protection is required for 40A circuits, and it accommodates feed-through terminations for easy integration into existing switchgear or MCC assemblies.
