This is a DC-only breaker (the supply frequency is listed as 0 Hz). The 250 VDC rated voltage and 10 kA breaking capacity define its application envelope: it protects a single DC bus or load branch, not an AC circuit. At 100 A, this is a high-current single-pole DC breaker; most SENTRON 5SL series MCBs top out at 20 A or 16 A on AC. The 1.5 modular width units (27 mm wide) mean it occupies one-and-a-half standard 18 mm DIN-rail positions, so check your panel layout — it will not fit a single-width slot.
The 70 mm depth and 90 mm height match the SENTRON 5SL and 5SP family footprint, so it aligns with adjacent breakers in a multi-pole arrangement. IP20 with connected conductors — suitable for enclosed panel installation, not for wet or washdown environments. Tunnel terminals top and bottom accept copper conductors; halogen-free and silicon-free construction avoids outgassing concerns in sealed enclosures.
Supplementary devices and mechanical endurance
Shock resistance tested to 150 m/s² at 11 ms half-sine, vibration resistance to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) — robust enough for industrial machinery and transport applications.
