Schneider Electric MG24435 Molded Case Circuit Breaker

Schneider Electric MG24435 Molded Case Circuit Breaker (Merlin Gerin) is a 20 A, 1-pole, thermal-magnetic protective device designed for DIN rail mounting in industrial electrical distribution panels, where it serves to interrupt fault current and prevent damage to power circuits and connected equipment while fitting neatly into compact control enclosures. Rated at 480Y/277 VAC and operable at 50/60 Hz, it uses a C-curve trip characteristic to balance fast fault clearance with selective protection for general-purpose circuits such as lighting, HVAC equipment, motors, and automation hardware in commercial facilities and industrial plants. Its DIN rail mounting and compact form factor enable quick installation in distribution panels, switchboards, and control cabinets, supporting reliable protection across electrical distribution networks and helping maintenance teams perform replacements, retrofits, or expansions with minimal downtime and consistent reliability. For project planning and cross-reference, common replacements include Schneider Electric Multi 9, ABB S200 Series, and Siemens 5SY Series, illustrating the MG24435’s compatibility with standard industrial protection architectures and interoperability within mixed-brand panels.
