Odklopniki za ozemljitveni uhajavi tok

Proizvodi namenjeni za zaščito pred preobremenitvijo, kratkim stikom, ozemljitvenim uhajavim tokom in pred električnimi udari v nizkonapetostnih tokokrogih. Serija WS-V kot najnovejša serija nizkonapetostnih stikal nudi številne variante vključujoč stikala tipa F, ki se kljub majhnim dimenzijam odlikujejo z izboljšano uporabnostjo.

Odklopniki za ozemljitveni uhajavi tok (ELCB) NV

Ta stikala se koristijo za zaščito pred nevarnostjo električnega udara in za preprečitev požara. Poleg tega imajo enake funkcije kot stikala MCCB.
