6 A B-curve — the load and fault ceiling for this 2-pole MCB
The ABB 2CCS472001R0065 is a 2-pole miniature circuit breaker rated 6 A with a B tripping characteristic, meaning the magnetic trip operates between 3 and 5 times the rated current — 18 A to 30 A — before the thermal bimetal handles sustained overloads. For a 6 A branch circuit feeding resistive loads like lighting or small heating elements, this curve clears fast enough to protect the cable without nuisance tripping on the modest inrush these loads draw. The short-circuit breaking capacity is 10 kA for both Icn (rated) and Icu (ultimate) at 440 V — the breaker safely interrupts a fault up to that level without welding its contacts or cascading failure upstream. In a typical 230 V single-phase distribution board fed from a 10 kA-rated upstream device, this MCB coordinates without needing a current-limiting fuse ahead of it.
DIN rail footprint and panel integration
Snap-on DIN rail mount (EN 60715) — the 69 mm width occupies two standard 17.5 mm module spaces. The 89 mm height and 94.5 mm depth fit inside a standard 4-module enclosure with room for wiring bends above and below the terminals. Screw terminals accept up to 25 mm² conductor; the IP20 finger-safe housing means it is intended for enclosed distribution boards, not open-panel or washdown locations. Overvoltage category III rating confirms it is designed for fixed installation downstream of the main distribution board — the impulse withstand level matches the transient environment of a building's final subcircuits.
