Schneider Electric's MG24503 Miniature Circuit Breaker is a 1-pole, 4-amp protective device in the Multi9 MG family designed for DIN-rail installations. It is rated for 120/277 VAC circuits and employs a thermal-magnetic trip with a D-type curve to respond to overloads and short circuits. The unit features a lever-operated mechanism and box lug terminals for secure connections, and carries UL 1077 recognition as a supplementary protector. This MG24503 is commonly used in control panels and enclosures where compact, reliable single-pole protection is required.
