switch discon­nec­tors with fuses for a perfect system

A user-inde­pen­dent jump switchgear with manual or motor drive ensures a clearly defined switching speed, and with that a switching capacity of up to 120kA. Exten­sive acces­sories installed ex works in 2‑, 3- or 4‑pole versions allow a high degree of flex­i­bility in plant plan­ning. SASILplus creates safe and reli­able low-voltage main distributions.

Regard­less of where energy is to be distrib­uted safely, SASILplus ensures the energy supply is not only safe, but reli­able as well. 


As the strip auto­mat­i­cally produces a contact, it only needs to be pushed into place. No fiddly, millimetre-precise posi­tioning; no securing with screws –simply attach the strip guide and push SASILplus in like a drawer.


You will also notice the weight advan­tage of SASILplus when you install it, as you can quickly inte­grate or replace the strips in large switch cabinet open­ings by inser­tion, even under tension.


Because we at JEAN MÜLLER like to think ahead and also consider things from our customers’ point of view, we incor­po­rate addi­tional safety features that also make their work easier. Our inter­lock func­tion prevents strips from being inad­ver­tently being installed or removed when they are switched on.
