It occupies one modular width unit (18 mm) on a DIN rail, with a 76 mm depth and 90 mm height — fits standard 1-module cutouts in SENTRON distribution boards or any 35 mm DIN-rail enclosure.
The 10 kA rating under IEC 60898-1 is the standard for domestic and light commercial distribution; the 35 kA under IEC 60947-2 is the industrial rating that tells a panel builder this MCB can clear higher prospective fault currents in an industrial supply. Operating temperature range of -40 °C to 75 °C covers most outdoor and unheated plant environments, though the derating curve above 40 °C (max 95% RH at 55 °C, dropping to 35% at 75 °C) means the breaker's thermal trip may shift — factor that into the load calculation if the panel sits near a furnace or in direct sunlight.
Installation depth is 70 mm (the body is 76 mm deep, but the 70 mm figure accounts for the rail and wiring space).
Certified to IEC / EN 60898-1 (the general MCB standard for household and similar installations) and IEC / EN 60947-2 (the industrial circuit-breaker standard for higher fault levels). Also carries UL 1077 and CSA C22.2 No. 235 recognition — the 5 kA rating under UL 1077 is the North American supplementary-protector rating, which means it's accepted as a branch-circuit protective device in UL 508A industrial control panels when used within its marked interrupting rating.
