Schneider Electric MGN61349N Molded Case Circuit Breaker

Schneider Electric's Square D MGN61349N molded‑case circuit breaker is a two‑pole, 5 A device rated for 480Y/277 V operation, designed to protect branch circuits in commercial and light‑industrial panels. It employs a thermal‑magnetic trip mechanism to provide overload and short‑circuit protection, and is part of the Square D MGN family, compatible with Schneider Electric distribution products and enclosure systems. The MGN61349N model designation identifies this specific low‑ampacity MCCB, with a compact form factor suitable for installation inside distribution panels where space is limited. The 480Y/277 V rating supports installations derived from a 480 V three‑phase system with a 277 V line‑to‑neutral, enabling protection of circuits in environments such as offices, data centers, and light manufacturing facilities that utilize high‑voltage distribution. This breaker is intended for protecting branch circuits in 480 V distributions, providing reliable interruption of current when preset limits are exceeded to help prevent damage to wiring and connected equipment.
