It is a 2-pole, 40 A unit with a K trip curve, clips onto DIN rail, and occupies 4 modular pitches (36 mm wide, 81 mm tall, 73 mm deep). The thermal-magnetic trip unit handles the overload side; the magnetic element clears short-circuits. This is not a general-purpose AC breaker — it is rated and tested for DC only, with a utilisation category A per EN/IEC 60947-2. Breaking capacity is the key fit check: 20 kA Icu at 220 V DC and 250 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC. Rated insulation voltage (Ui) is 500 V DC, and the rated operational voltage (Ue) covers 220 V, 250 V, 440 V, and 500 V DC systems. Mounts via clip-on to DIN rail. The terminals can also accept two or three conductors per pole — useful for daisy-chaining downstream loads without extra terminal blocks. IP20 on the terminals, IP40 on the modular enclosure — suitable for dry indoor panels. The toggle switch provides local ON/OFF indication, and the contact position indicator confirms isolation status (suitability for isolation is marked on the device). Padlockable for lockout/tagout. Standards compliance: EN/IEC 60947-2. Tropicalisation per IEC 60068-2 (class 2) means it withstands humidity up to 95 % at 55 °C.","metaTitle":"MGN61889 Multi9 C60H-DC MCB, 40 A, 2P, K Curve, 20 kA DC","metaDescription":"Schneider Multi9 C60H-DC MGN61889 miniature circuit-breaker, 40 A, 2-pole, K curve, 20 kA breaking at 250 V DC.
