D-curve selectivity for motor and transformer branch circuits
The Schneider Electric C60H4P10AD is a Multi9 C60H miniature circuit breaker with a D tripping curve, rated 10 A at 40 °C, and 4 protected poles. The 4-pole configuration suits three-phase plus neutral applications, common in European panel builds.
Breaking capacity and selectivity coordination
Beyond the 10 kA Icn per EN 60898, the C60H4P10AD carries higher Icu ratings under IEC 60947-2: 30 kA at 230–240 V AC, 15 kA at 400–415 V AC, and 10 kA at 440 V AC. For DC circuits, it handles 25 kA at 125 V DC (2-pole series) and 40 kA at 125 V DC (3-pole series). These figures let the site engineer verify selectivity with upstream devices without oversizing the entire sub-distribution.
DIN-rail integration and panel fill
The C60H4P10AD snaps onto a 35 mm symmetrical DIN rail and occupies 8 modules of 9 mm pitch, for a total width of 72 mm. Depth is 73 mm, height 81 mm. The fixed mounting mode and toggle control are standard for distribution boards.
The C60H4P10AD is certified to IEC 60947-2 and EN 60898. Rated insulation voltage (Ui) is 500 V AC; rated operational voltage per pole is 60 V DC. Maximum operating altitude is 2000 m. Compliance documentation (declarations of conformity, CE marking) is available from the manufacturer's document portal for the Multi9 C60H series.
