The indoor isolating switches given in this list are for switching with no-current. They are produced under the technical knowledge of FRITZ DRIESCHER / Moosburg (Germany), and have positively proven themselves in many installations with their superior quality. They have a robust basic frame of welded profiled steel. Double isolating knives are made of copper, nickel or silver plated. The contact is effected by cutoff and turning'point by means of distingue line contact. Rich sized cross sections and appropriate contact pressure guarantee a safe and easy operation for a long period of years.

* The making capacity is limited by 40 kA.
**The making capacity is limited by 31.5 kA
The earthing switch can be quick-action
if desired.
Making and breaking is realized by a spring action. |
SINGLE - or
- 3-POLE
FUSE BASE
They are designed for use mV-Fuses in compliance with
the standards DIN 43625,
TS 1259- IEC 60282-I
Rated current of the contact system is 200 Amp.
Without Breaking Mechanism
Type ADO : Suitable for HV-Fuses with optical indicator
With Breaking Mechanism
Type ADM/.. : Suitable for HV-Fuses with Striker Pin. It gives the advantages
of getting an impulse for an alarm system / or for a shunt
release, by means of a switch (4-12 poles)
