The MGN61815 is a Schneider Electric Multi9 C60H-DC 2-pole DC miniature circuit breaker rated 13 A at 50 °C (curve B) with a breaking capacity of 20 kA Icu at 220 V DC per EN/IEC 60947-2.
Curve B means the magnetic trip fires at 3 to 5 times In (here 5.5 x In ±20% DC per the spec), so it handles short-circuit faults fast — good for protecting DC loads like control circuits, solenoids, or small DC drives where you want selectivity against upstream devices. The thermal-magnetic trip unit covers overload (thermal) and short-circuit (magnetic) in one package. Rated insulation voltage (Ui) is 500 V DC, and the operational voltage (Ue) covers 220 V DC, 250 V DC, 440 V DC, and 500 V DC — so it works on common DC bus voltages up to 500 V.
Clip-on DIN rail mount, 36 mm wide (4 modules), 81 mm tall, 73 mm deep. IP20 finger-safe front, IP40 inside the modular enclosure. Padlockable toggle for lockout/tagout. ON/OFF indicator visible through the front.
