The SENTRON 5SY3016-7KV is a compact miniature circuit breaker (MCB) in a 1+N-pole configuration, rated 16 A with a C tripping characteristic. Its breaking capacity is 4.5 kA at 230 V AC per EN 60898, sufficient for residential and light commercial distribution boards where the prospective short-circuit current stays within that limit.
Installation depth is 70 mm; the compact design occupies a single width unit (18 mm), leaving room for adjacent modules in the same enclosure.
