This MCB snaps onto a standard 35 mm DIN rail and occupies 1 modular width unit (18 mm) — that's the narrowest possible footprint for a 4-pole breaker, so it leaves room in a crowded panel. Depth is 76 mm, height 90 mm, and the installation depth behind the panel face is 70 mm. Mounting position is unrestricted, and the IP20 rating (with conductors connected) is typical for enclosed distribution boards — no special sealing needed inside a cabinet. The 10,000 mechanical operating cycles typical service life means this breaker is built for the switching frequency of a distribution board — not a daily-switched load, but fine for occasional isolation and fault clearance. The 2.73 W power loss per pole at rated current in hot operating state adds up to about 11 W total for the 4-pole unit — negligible for thermal management in a standard enclosure, but worth noting if you're packing many breakers into a small, sealed box.","metaTitle":"Siemens 5SL4432-7RC SENTRON MCB, 4P C 32A 10kA 415V","metaDescription":"Siemens 5SL4432-7RC SENTRON miniature circuit breaker, 4-pole, C-curve, 32 A, 10 kA at 415 V AC.
