The 90 mm height fits standard 100 mm deep enclosures. IP20 with connected conductors means the busbar and wiring provide the touch protection; the breaker body alone is finger-safe only when wired. Rated for mechanical engineering and industrial environments per the suitability listing.

No — the 5SY8416-8BB08 is a 4-pole D-curve 16 A breaker with magnetic-only trip, while the 5SY3132-6 is a different pole count and characteristic. The DIN-rail footprint (4 width units) may match, but the terminal arrangement and trip curve differ; verify the existing panel's wiring diagram before substituting.
The breaker carries IEC 60947-2 (30 kA) and UL 1077 / CSA C22.2 No.235 (5 kA) ratings, with overvoltage category III. The SENTRON series typically provides CE, UKCA, and EAC declarations; specific RoHS/REACH statements are available from Siemens documentation for this order code.
