DC-rated MCB for photovoltaic and battery banks
The MGN61891 is a Schneider Multi9 C60H-DC miniature circuit breaker — a 2-pole, 63 A thermal-magnetic unit with a K curve, purpose-built for DC networks. It's rated 63 A at 50 °C per EN/IEC 60947-2, with a breaking capacity of 20 kA Icu at 250 V DC and 10 kA Icu at 440 V DC.
At 440 V DC the Icu drops to 10 kA, so verify your available fault current if you're using it on a 440 V battery bank. The K curve (12 x In magnetic trip) means it won't nuisance-trip on capacitor charging or motor inrush, but it's not for highly inductive loads — those need a Z curve.
Tunnel terminals accept up to 35 mm² rigid stranded or 25 mm² flexible — strip 14 mm, torque to 3.5 N·m. The IP20 finger-safe front and IP40 modular enclosure are standard for enclosed distribution boards. Padlockable toggle for lockout/tagout.
