Square D FAL34020 Three Pole Molded Case Circuit Breaker

The Square D FAL34020 is a three‑pole molded‑case circuit breaker rated for 20 A in a 480 V system, part of Square D’s FAL series and designed for industrial or commercial power‑distribution panels that require reliable three‑phase protection. It uses a thermal‑magnetic trip unit (LI trip) to provide coordinated long‑time and instantaneous protection, with an 18 kA short‑circuit interrupting rating at 480 V. This model is a feed‑through‑lug type with line and load side lug terminals and is suitable for copper or aluminum conductors, enabling straightforward wiring in panel boards and switchgear assemblies. The FAL34020 is compatible with Square D installations that accept this catalog number, and its three‑pole configuration supports balanced protection of all three phases in 480 V networks, making it a common choice for protecting feeders to motors, transformers, and other three‑phase loads in commercial and light industrial applications.
