Product details

DC-rated miniature circuit breaker for distribution

The MGN61817 is a Schneider Electric Multi9 C60H-DC miniature circuit breaker rated 20 A at 50 °C per EN/IEC 60947-2, with a B curve magnetic trip at 5.5 x In ±20 % DC. It protects DC circuits up to 500 V rated operational voltage, with breaking capacities of 20 kA Icu at 250 V DC and 10 kA at 440 V DC — enough to handle fault currents in battery banks, solar arrays, and DC distribution panels.

Tunnel terminals accept 1…25 mm² rigid stranded or 1…16 mm² flexible, with a tightening torque of 2.5 N·m. The IP20 finger-safe front and IP40 modular enclosure suit enclosed distribution boards.

DC application specifics

Rated insulation voltage 500 V DC, pollution degree 3 per EN 60947-2. Suitable for isolation (yes, per standard). Thermal-magnetic trip unit, 2 protected poles, toggle control with ON/OFF indication. Padlockable for lockout/tagout. Electrical durability 3000 cycles at L/R = 2 ms; mechanical durability 20,000 cycles.

Frequently asked questions

What is the breaking capacity of MGN61817 at 250 V DC?

20 kA Icu at 250 V DC per EN/IEC 60947-2. At 440 V DC it is 10 kA, and at 500 V DC it is 6 kA.

What is the closest alternative to MGN61817 in the same family?

Within the Multi9 C60H-DC range, the closest alternative would be a different current rating (e.g., 16 A or 25 A) or pole count. The MGN61817 is a 20 A, 2-pole DC version with B curve — any substitution must match the DC voltage rating, breaking capacity, and curve code for the specific circuit.

Where can I buy MGN61817 and what is the lead time?

The MGN61817 is sourced to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price.

What compliance standards does MGN61817 meet?

Certified to EN/IEC 60947-2, pollution degree 3. Tropicalisation class 2 per IEC 60068-2. IP20 finger protection (IP40 in modular enclosure). No earth-leakage protection built in.
