Schneider Electric WL3CCR43A3CFBFXPEA Circuit Breaker

Schneider Electric WL3CCR43A3CFBFXPEA is a Square D Masterpact NW12H three‑pole, 1200‑amp insulated‑case circuit breaker designed for draw‑out mounting in industrial power‑distribution gear. As part of the NW family, this 3‑phase device provides overcurrent protection for large circuits in switchboards, motor control centers, and process equipment, with a short‑circuit current rating up to 100 kA at 480 V. The draw‑out mounting enables safer maintenance and quicker replacement within heavy‑duty panels. With a 1200 A nominal rating, it serves as a feeder or main breaker in sizable distribution panels that handle substantial current. The WL3CCR43A3CFBFXPEA designation ties to Schneider Electric’s Square D NW12H lineup, a configuration known for its high interrupting capacity in industrial environments. Typical applications include manufacturing facilities, processing plants, and other systems requiring reliable protection for high‑fault‑current three‑phase circuits. Designed for 480 V three‑phase systems, it is commonly used as a main protection device in large enclosures and switchgear assemblies.
