The Siemens SENTRON 5SY4106-8CC11 is a 1-pole miniature circuit breaker with a D tripping characteristic, rated 10 kA breaking capacity per EN 60898 at 400 V AC and 72 V DC maximum. Designed for railway applications, it mounts on a DIN rail (1 modular width unit, 18 mm wide) and accepts any mounting position. The D-curve means it tolerates high inrush currents — typical for motor or transformer loads — without nuisance tripping, while still clearing a short-circuit fault up to 10 kA.
Integration & Mounting
Snap-on DIN rail mount, 1 MW (18 mm wide). Installation depth 70 mm; overall depth 76 mm. Combined terminals top and bottom accept busbar or wire. Sealable — allows tamper-proofing in metering or safety circuits. Halogen-free and silicon-free construction matters for clean-room or semiconductor fab environments where outgassing contaminates processes.
