- Has built-in overcurrents protection system, provides automatic switch-off at overload currents and short circuits. S-type characteristics of instantaneous release device (break-time at 10 In current is no more that 0,1 s).
- Breaking differential current regulation during the operation is impossible.
- Modifications with nominal current from 10 up to 63 A.
- Nominal make-and-break capacity is 3000 A.
- Withstands standard environment (type U 3.1).
