Product details

DC-rated miniature circuit-breaker for distribution panels

The Schneider Electric MGN61890 is a Multi9 C60H-DC miniature circuit-breaker built for DC network protection in distribution applications. It carries a 50 A rated current at 50 °C per EN/IEC 60947-2, with a K-curve magnetic trip threshold of 12 x In ±20 % DC — meaning it handles moderate inrush without nuisance tripping, suited for DC motor or transformer branch circuits. Clip it onto a DIN rail in a standard 36 mm (4 x 9 mm pitches) footprint — fits a typical distribution board slot.

Breaking capacity is given at four DC voltages: 20 kA at 220 V DC, 20 kA at 250 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC. Match your system voltage to the closest column — if your fault current exceeds that number at your voltage, this breaker isn't the right choice. The thermal-magnetic trip unit is non-interchangeable; what you see is what protects the circuit.

The enclosure is IP20 (fingers) and IP40 inside a modular enclosure — fine for a distribution board, not for washdown. The toggle provides ON/OFF indication and the unit is padlockable for lockout/tagout. The contact position indicator gives visual confirmation of the state.

Frequently asked questions

What is the breaking capacity of MGN61890 at different DC voltages?

The MGN61890 has a breaking capacity of 20 kA Icu at 220 V DC, 20 kA Icu at 250 V DC, 10 kA Icu at 440 V DC, and 6 kA Icu at 500 V DC, all per EN/IEC 60947-2.

What does curve K mean on this DC MCB?

Curve K means the magnetic trip threshold is 12 x In ±20 % DC. This is higher than B or C curves, so the breaker tolerates moderate inrush currents from DC motors or transformers without nuisance tripping.

Where can I buy MGN61890 and how is it quoted?

The MGN61890 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quotation.
