Schneider Electric MG24452 Molded Case Circuit Breaker

Schneider Electric MG24452 Multi9 C60 UL1077 MCB is a two-pole miniature circuit breaker rated for 20 A on 480Y/277 VAC systems, with a C-curve trip characteristic and a 5 kA short-circuit rating. It is UL 1077 listed and designed for DIN-rail mounting in control panels and commercial/industrial distribution boards, where 2P overcurrent protection is required. The MG24452 supports a 480Y/277 VAC supply and also carries a 125 V DC rating, enabling mixed AC/DC control circuits in modern panels. Part of Schneider Electric's Multi9 family, it provides a compact 2P protection solution suitable for circuits handling lighting, receptacles, and small loads on multi-voltage distributions in commercial buildings and light industrial environments. With a C-curve tripping profile, it tolerates brief surges and coordinates with upstream protection in systems designed around 20 A devices.
