Product details

What this MCB does and where it fits

The Siemens SENTRON 5SP4191-8 is a 1-pole miniature circuit breaker rated 100 A with D-curve tripping characteristic, breaking 10 kA at 400 V AC per EN 60898. The 27 mm width (1.5 modular units) saves rail space compared to a standard 2-module breaker.

Environment and compliance details

Pollution degree 3 (industrial environment with conductive contamination). IP20 with conductors connected, IP40 at the handle area with a distribution cover.

Fastens via DIN rail or screw fixing; mounting position any. Installation depth 70 mm, overall depth 76 mm. Tunnel terminals top and bottom. Sealable (can be locked in OFF position for lockout/tagout). Supplementary devices can be installed on the side.
