Schneider Electric MGN61365 Miniature Circuit Breaker

Schneider Electric MGN61365 Miniature Circuit Breaker is a three‑pole Multi9 device from the C60 family, rated 20 A at 480Y/277 V AC with a D‑curve trip characteristic. This UL489‑listed MCB provides overload and short‑circuit protection for three‑phase circuits, delivering up to 10 kA interrupting capacity (10 kA UL489 and 10 kA IEC/EN 60947‑2). The MGN61365 corresponds to the C60BP variant within the Multi9 line and carries the 480Y/277 V rating. It was discontinued on February 17, 2021, with end‑of‑service on June 15, 2021, and is not normally stocked in distribution facilities. Schneider Electric notes a replacement: M9F43320, another 3P, 20 A, D‑curve MCB in the Multi9 family with the same 10 kA interrupting capacity. The 480Y/277 V rating indicates suitability for circuits connected to 480Y/277 V systems, where reliable protection for three‑phase feeders is required, and it forms part of Schneider Electric's modular Multi9 protection portfolio.
