The MGN61833 is a Schneider Electric Multi9 C60H-DC miniature circuit breaker — a 1-pole, 16 A rated, C-curve unit built specifically for DC networks. The headline breaking capacity is 20 kA Icu at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC — all conforming to EN/IEC 60947-2. The thermal-magnetic trip unit uses a C-curve with a magnetic tripping limit of 8.5 x In ±20% DC, so it holds moderate inrush from DC loads like contactor coils or solenoid valves while still tripping fast on a hard short.
DC-rated breaker — what that means for the panel
This is a DC-only breaker (network type: DC), not a dual-rated AC/DC unit. The rated operational voltages are 110 V DC, 220 V DC, and 250 V DC, with an insulation voltage of 500 V DC. The 1-pole configuration switches the positive line; for a two-wire DC circuit (positive and negative), you need two units ganged or a 2-pole variant. The IP20 finger-safe front and IP40 modular enclosure let it sit in a standard distribution board without extra shrouding. It is padlockable and provides local ON/OFF indication with a contact position indicator — useful for lockout/tagout during panel maintenance.
