Schneider Electric MGN61365 Molded Case Circuit Breaker

Schneider Electric MGN61365 is a three-pole Miniature Circuit Breaker (MCB) in the Multi9 C60 UL489 family, rated 20 A for 480Y/277 V three‑phase distribution. This D‑curve device delivers thermal‑magnetic protection with a 10 kA interrupting rating at 480 V and is UL489 listed (CSA certified) for use in Schneider Electric distribution systems. As a legacy part, it was discontinued for commercialization on February 17, 2021, with end‑of‑service documented June 15, 2021. For continued availability within the same protection platform, Schneider Electric lists M9F43320 as the recommended replacement in the Multi9 family. Typical applications include protection of three‑phase feeders in commercial buildings, data centers, and light‑industrial panels that operate at 480Y/277 V, where compact 20 A magnetic‑thermal overcurrent protection is required.
