Square D FHL36015 BU Three-Phase Circuit Breaker

The Square D FHL36015 BU is a three‑pole molded‑case circuit breaker (MCCB) from Square D’s FHL frame family, rated for 15 amperes at up to 600 volts. It uses a thermal‑magnetic trip unit for both overload protection and short‑circuit interruption, with a non‑interchangeable trip mechanism and line and load end terminals designed for bolt‑on mounting. It delivers substantial interrupting capacity for a 3P device: 65 kA at 240 VAC, 25 kA at 480 VAC, and 18 kA at 600 VAC, making it suitable for protecting feeders and motors in industrial power distribution. Ideal for 600 V three‑phase systems in commercial and industrial environments, this MCCB provides reliable overcurrent protection while fitting standard Square D enclosure and bus configurations.
