Schneider Electric NE-3829 Molded Case Circuit Breaker

The Schneider Electric NE-3829 Molded Case Circuit Breaker is a legacy Square D MCCB from the NE family, designed to provide overcurrent protection in low‑voltage distribution panels. The NE series (along with NA, NH, NC, and NX variants) is listed by Schneider Electric as legacy equipment, with obsolescence noted since 2009. The NE‑3829 designation identifies an older MCCB style used to safeguard feeders and main circuits in industrial and commercial electrical systems, where a compact, field‑installed protection device was appropriate for the panel design of its era. As a discontinued model, exact factory specifications for new procurement may not be guaranteed by current product lines, so verifying any available data with a legacy catalog or distributor is advised. This device was chosen in its time for its protection characteristics within Schneider Electric's Square D ecosystem, where it was compatible with panels and mounting arrangements of its generation. For ongoing reliability and easier sourcing in modern projects, engineers typically reference Schneider Electric's current MCCB families in place of obsolete NE products, ensuring compliance with current standards and panel requirements while maintaining the protective roles MCCBs deliver in low‑voltage distribution networks.
