Rated 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, so it safely interrupts faults up to those levels without cascading upstream. The 15 kA figure under the industrial standard gives headroom for higher fault-current panels. Also rated for DC circuits up to 60 V, which covers control-voltage supplies and signal loops common in automation racks.
Built for the nacelle — wide temperature and vibration
Vibration resistance rated at 50 m/s² over 25 to 150 Hz and 60 m/s² at 35 Hz (4-second dwell). That is enough to handle the shake from gear mesh and blade pass frequencies without the breaker tripping or the contacts fretting. No up-tower swaps needed if the turbine is within those limits. Halogen-free and silicon-free construction, which matters in enclosed panels where outgassing could corrode nearby contacts or sensitive electronics.
Width is 18 mm (1 modular unit), depth 70 mm, height 121 mm. Snaps onto standard DIN rail; mounting position any orientation. Sealable design allows padlocking in the OFF position for lockout/tagout procedures. IP20 with conductors connected, IP40 in the handle area — fine for dry indoor panels; not rated for washdown.
