Product details

DC-rated MCB for distribution panels

The Schneider Electric MGN61838 is a Multi9 C60H-DC miniature circuit breaker rated 40 A at 50 °C, single-pole, with a C-curve trip characteristic. It is designed for DC network distribution and mounts via clip-on onto a DIN rail, occupying 2 x 9 mm pitches (18 mm wide). Breaking capacity is rated per EN/IEC 60947-2: 20 kA Icu at 110 V DC, 10 kA Icu at 220 V DC, and 6 kA Icu at 250 V DC. This makes it suitable for DC distribution applications where high fault currents are possible, such as in industrial control panels or telecom power plants. The 1-pole configuration protects a single DC line, with the neutral or return path handled separately.

Integration notes

The 18 mm width (2 modules) fits standard enclosure spacing. IP20 finger protection on the front; IP40 within a modular enclosure. The toggle switch provides local ON/OFF indication, and the unit is padlockable for lockout/tagout procedures.

Rated insulation voltage (Ui) 500 V DC. Pollution degree 3 per EN 60947-2.

Frequently asked questions

Where can I buy MGN61838 and how do I get a price?

MGN61838 is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not from a published list.

What is the breaking capacity of MGN61838 at 110 V DC?

The breaking capacity is 20 kA Icu at 110 V DC per EN/IEC 60947-2. At 220 V DC it is 10 kA Icu, and at 250 V DC it is 6 kA Icu.

What is the closest alternative to MGN61838 in the C60H-DC range?

Within the same C60H-DC series, the closest alternative would be a different rated-current variant (e.g., 32 A or 50 A) with the same 1-pole C-curve DC rating and physical footprint. No pin-compatible drop-in replacement exists outside this series; verify the required current and breaking capacity before specifying a substitute.
