  • General
  • Technical Table
  • Documentation

The MC169 and MC259 breakers have respectively 160A and 250A rated current, in the same size. They can be equipped with thermomagnetic or electronic protection relay, type Line protection, Generator, Magnetic motor protection, isolator.
The electronic protection is a new generation of trip unit, with a very wide range of threshold (from 0,3 to 1 In), and many functions like LS (Long time delay, Short time delay), LSI (with additional Istantaneus protection channel), LSIG (with Ground protection channel).
On the front of the trip unit, there is a micro USB port where it is possible to connect a PC and supply the unit to check the tripping functions.
All the electronic type breakers have the possibility to adjust the Neutral protection as 0%, 50%, 100% of the rated current.
