Square D FAL36015BU3 Circuit Breaker

Square D FAL36015BU3 is a three-pole molded‑case circuit breaker from Schneider Electric's Square D FA/FAL family, rated for 15 A with a maximum voltage of 600 V (AC) and intended for three‑phase distribution in commercial and industrial panels. It employs a thermal‑magnetic trip unit with fixed long‑time and instantaneous protection, and features line and load lug terminals for straightforward installation within compatible enclosures. The device delivers an 18 kA interrupting capacity at 480 V, and supports feed‑through mounting in suitable switchgear, making it suitable for panelboard and distribution feeder protection where space and adaptability matter. As a BU3 variant of the FA/FAL family, it serves as a direct, code‑compliant replacement option for older F‑Frame breakers in many retrofit projects and is commonly used in 3‑phase circuits up to 15 A.
