It carries a C tripping characteristic, which means it handles moderate inrush currents typical of motor starters and small transformers without nuisance tripping — a solid fit for general-purpose loads in mechanical engineering and industrial environments. Rated breaking capacity is 10 kA per EN 60898 at 400 V AC, and 15 kA per IEC 60947-2 — the higher figure applies when the breaker is installed per the standard's industrial rules, giving you a safety margin for high-fault locations near the main distribution. AC rated voltage is 400 V, DC rated voltage is 60 V, and insulation voltage (Ui) is 440 V AC.
The 5SJ4108-7HG40 is halogen-free and silicon-free, which simplifies compliance documentation for RoHS and REACH declarations — a plus for quality and documentation teams tracking material restrictions.
Installation Notes
Vibration resistance is 50 m/s² at 25 to 150 Hz and 60 m/s² at 35 Hz (4-second duration) — adequate for most industrial machinery but not for extreme high-vibration applications like crushers or large reciprocating compressors without additional support. The sealable design allows padlocking in the OFF position for lockout/tagout procedures.
