Product details

The Schneider Electric MGN61889 is a Multi9 C60H-DC miniature circuit-breaker for DC networks. It is a 2-pole, 40 A unit with a K trip curve, clips onto DIN rail, and occupies 4 modular pitches (36 mm wide, 81 mm tall, 73 mm deep). The thermal-magnetic trip unit handles the overload side; the magnetic element clears short-circuits. This is not a general-purpose AC breaker — it is rated and tested for DC only, with a utilisation category A per EN/IEC 60947-2. Breaking capacity is the key fit check: 20 kA Icu at 220 V DC and 250 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC. Rated insulation voltage (Ui) is 500 V DC, and the rated operational voltage (Ue) covers 220 V, 250 V, 440 V, and 500 V DC systems.

Mounts via clip-on to DIN rail. The terminals can also accept two or three conductors per pole — useful for daisy-chaining downstream loads without extra terminal blocks. IP20 on the terminals, IP40 on the modular enclosure — suitable for dry indoor panels. The toggle switch provides local ON/OFF indication, and the contact position indicator confirms isolation status (suitability for isolation is marked on the device). Padlockable for lockout/tagout.

Standards compliance: EN/IEC 60947-2. Tropicalisation per IEC 60068-2 (class 2) means it withstands humidity up to 95 % at 55 °C.

Frequently asked questions

What is the breaking capacity of the MGN61889 at 250 V DC?

20 kA Icu at 250 V DC per EN/IEC 60947-2. At 440 V DC it drops to 10 kA, and at 500 V DC to 6 kA. Verify your available fault current against these ratings before specifying.

What does the K curve mean on this DC MCB?

The K curve sets the magnetic trip threshold at 12 x In (±20 %). This is designed for DC circuits with high inrush currents — motor loads, solenoids, power supplies — where a B or C curve would trip on startup. The thermal element handles overloads; the magnetic element clears short-circuits.
