DC-rated MCB for 1-pole distribution
The MGN61829 is a 1-pole C60H-DC miniature circuit breaker from the Multi9 range, rated 6 A at 50 °C with a C curve (8.5 x In magnetic tripping limit, +/- 20 % DC) and a breaking capacity of 20 kA Icu at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC per EN/IEC 60947-2. The thermal-magnetic trip unit handles DC networks only — this is not an AC-rated device.
Breaking capacity and isolation
At 110 V DC the Icu is 20 kA, dropping to 10 kA at 220 V DC and 6 kA at 250 V DC. Rated insulation voltage (Ui) is 500 V DC; rated operational voltage (Ue) covers 110 V DC, 220 V DC, and 250 V DC.
Terminal and mounting details
Tunnel-type terminals accept 1 to 25 mm² rigid stranded (AWG 18 to AWG 4) on top or bottom, with a tightening torque of 2.5 N.m. Strip length is 14 mm. IP20 finger protection (IP40 in modular enclosure) and padlockable toggle for lockout/tagout.
