The C60H4P32AC is a 4-pole miniature circuit breaker from Schneider Electric's Multi9 C60 range, rated 32 A at 30 °C with a C-curve magnetic trip (5 to 10 x In). The 10 kA Icn at 230/400 V AC per EN 60898 is the rated short-circuit capacity for the breaker under standard conditions; the higher Icu values (up to 30 kA at 230–240 V AC per IEC 60947-2) cover industrial fault levels. For a 4-pole breaker, the 32 A rating and C-curve suit sub-distribution boards where the downstream load includes small motors, lighting, and socket outlets. The thermal-magnetic trip unit combines a bimetal element for overload protection and a solenoid for short-circuit response. The magnetic threshold at 5–10 x In means the breaker holds through transformer inrush and motor starting current without nuisance tripping, but clears fast on a hard fault.
The toggle control provides local ON/OFF indication and a contact position indicator confirms the state of the moving contacts for isolation verification. The tropicalisation treatment (class 2 per IEC 60068-1) and 95 % relative humidity rating at 55 °C make it suitable for unconditioned electrical rooms and outdoor-rated enclosures in humid climates.
Compliance documentation includes EN 60898 (household and similar installations) and IEC 60947-2 (industrial) standards. The limitation class 3 per IEC 60947-2 indicates energy-limiting performance that reduces let-through energy on faults.
