Specification and fit
The Schneider Electric C60H3P1AD is a 3-pole miniature circuit breaker from the Multi9 C60H range, rated 1 A at 40 °C with a D tripping curve. Breaking capacity is given per IEC 60947-2: 30 kA at 230–240 V AC, 15 kA at 400–415 V AC, and 10 kA at 440 V AC, with service breaking capacity (Ics) of 15 kA across the 12–440 V AC range. That Ics figure — the rating the breaker can clear and still be used again — is the one a coordination study cares about for selective coordination downstream. Mounts on a 35 mm symmetrical DIN rail, occupies 6 x 9 mm pitches (54 mm width), with tunnel terminals accepting up to 25 mm² rigid or 16 mm² flexible conductors.
Rated for operation at -25 to 60 °C ambient, storage from -40 to 70 °C, with 95 % relative humidity at 55 °C. Mechanical endurance is 20,000 cycles, which is standard for this class of distribution MCB.
