The Schneider Electric C60H2P20AC is a 20 A miniature circuit breaker from the Multi9 C60 range, built as a 1P+N unit with a C-curve trip characteristic (magnetic tripping between 5 and 10 times In). The thermal-magnetic trip unit combines a bimetal strip for overload protection and a solenoid for short-circuit protection.
Rated breaking capacity hits 10 kA Icu at 440 V AC, 15 kA at 400–415 V AC, and 30 kA at 230–240 V AC, all per IEC 60947-2. The limitation class is 3 per IEC 60947-2, meaning it lets through less energy during a fault than a class-2 or class-1 device. That helps with downstream coordination and reduces stress on wiring and connected equipment.
Width is 36 mm (4 x 9 mm pitches), which is the standard 2-module width for a 1P+N MCB in most enclosures. Depth is 73 mm, height 81 mm — check your enclosure depth if you are retrofitting into a shallow consumer unit. Wire stripping length is 14 mm.
