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. ## Lifecycle reality This part is marked obsolete by Schneider Electric.","metaTitle":"MGN19803 Acti9 OF/SD auxiliary contact, 6A, 230-400V AC","metaDescription":"MGN19803 Acti9 auxiliary contact from Schneider Electric. 1 C/O fault contact, 6A rated, 230-400V AC / 24-250V DC control.
