The C60H1P10AD is a 1-pole miniature circuit breaker from the Schneider Multi9 C60 series, rated 10 A at 40 °C with a D tripping curve (magnetic trip threshold 10–14 × In). The thermal-magnetic trip unit combines a bimetal strip for overload protection (heating up over seconds to minutes at moderate overcurrents) and a solenoid for short-circuit protection (instantaneous above the magnetic threshold). For a 10 A circuit feeding a motor starter or a small compressor, the D curve's wider magnetic band avoids tripping on the starting surge while still protecting the cable against sustained overload.
The 18 mm width (1 module pitch) means it occupies a single slot, so a 12-way enclosure holds 12 of these plus any auxiliaries. The terminals are rated for both copper and aluminium conductors — check local code for aluminium termination practice. The ON/OFF toggle provides local indication of contact position.
