Pomoćna oprema i dodatne komponente

Ovi proizvodi omogućuju proširenje funkcija prekidača. Na raspolaganju je raznovrsna dodatna opreme za unutarnju ili vanjsku ugradnju. Ovi dodaci mogu povećati sigurnost i funkcionalnost prekidača.

Dodaci za unutarnju ugradnju - AL, AX, SHT, UVT

Ove dodatke instaliramo unutar kućišta prekidača. AX je pomoćni kontakt prekidača i pokazuje stanje „otvorenosti“ ili „zatvorenosti“. Dodatak AL na pokazuje stanje stanja „isklapanja“. Dodatak SHT služi za daljinsko isklapanje prekidača. Dodatak UVT isklapa prekidač kod preniskog napona.

Dodaci za vanjsku ugradnju – poluge, TC, HL, MD

Ove dodatke instaliramo na vanjsku stranu kućišta. Služe za ručno uklapanje/isklapanje prekidača, blokadu, zaštitu i indikaciju stanja prekidača.
