The Schneider Electric MGN19803 is an Acti9-series auxiliary contact block — a double OC (open contact) or fault contact that signals the status of a companion circuit breaker or switch. It carries one C/O signal contact and is rated for 6 A at 230 V AC, 50 Hz, with a DC rating table that drops from 6 A at 24 V to 1 A at 250 V DC. The control circuit accepts 230...400 V AC 50/60 Hz or 24...250 V DC, so it works across both mains-voltage and low-voltage control schemes.
Snap-on DIN rail mount, 9 mm wide — one pitch on the rail, so it tucks into a crowded panel without eating up extra space. The bottom screw-clamp terminals accept 0.25...4 mm² rigid or 0.25...2.5 mm² flexible wire; tighten to 0.6 N·m. Strip 6 mm for the connection.
