The Siemens 5SP4191-6 is a 1-pole SENTRON miniature circuit breaker from the 5SP series, rated 100 A with a B tripping characteristic and a 10 kA breaking capacity per EN 60898 at 230/400 V AC. It occupies 1.5 modular width units (27 mm wide) on a DIN rail, with a 76 mm depth and 70 mm installation depth.
Fastens via DIN rail or screw fixing; mounting position is any. The 27 mm width (1.5 MW) and 76 mm depth leave room for adjacent breakers and wiring troughs in a standard distribution board. Tunnel terminals at top and bottom accept conductors without ferrule prep — strip length follows the terminal design, not a separate lug. IP20 with connected conductors, IP40 at the handle area with a distribution cover fitted.
Shock resistance per IEC 60068-2-27 at 150 m/s² for 11 ms half-sine; vibration resistance per IEC 60068-2-6 at 50 m/s² over 25–150 Hz. Halogen-free and silicon-free construction. Sealable for tamper evidence.
