The Schneider Electric C60H3P3AD is a 3-pole miniature circuit breaker from the Multi9 C60H series, rated 3 A with a D tripping curve.
The D curve magnetic trip operates at 10 to 14 times the rated current (In), so a 3 A breaker trips instantaneously between 30 A and 42 A. This suits loads with a starting surge well above running current — a small motor or a bank of fluorescent ballasts — without tripping on energisation. Breaking capacity is declared per IEC 60947-2: 30 kA Icu at 230-240 V AC, 15 kA at 400-415 V AC, and 10 kA at 440 V AC. Thermal-magnetic trip technology combines a bimetal strip for overload protection and a solenoid for short-circuit response. The limitation class is 3 per IEC 60947-2, meaning it limits let-through energy enough to protect downstream equipment in most fault scenarios.
Width is 54 mm (3 x 18 mm per pole), depth 73 mm, height 81 mm. Strip length is 14 mm.
