Schneider Electric MG24518 Miniature Circuit Breaker

Schneider Electric MG24518 Merlin Gerin two-pole miniature circuit breaker delivers overcurrent and short-circuit protection for industrial power circuits in DIN rail-mounted distribution panels, switchboards, and motor control centers. Rated 3 A at 480Y/277 VAC, it employs thermal-magnetic trip technology with a D-Curve characteristic to respond to overloads across 50/60 Hz systems. Its DIN rail mounting design supports straightforward installation in commercial and industrial facilities, safeguarding control circuits, instrumentation, lighting loads, and other electrical loads from faults. Common replacements include ABB S200 Series and Siemens 5SY Series, with Schneider Electric Multi 9 as another commonly referenced option.
