5. The initial operating current in the zone of the overload currents, multiples of the rated operational current of the RP-.
6. Set-point according to the response time in the overload current zone, s: -
7. Settings for the response time in the zone of short-circuit currents-any.
8. Settings for the operating current in the zone of short-circuit currents, multiples of the rated working current.
9. Rated short-time withstand current, kA 5.
10. Rated operating short-circuit breaking capacity, kA 7.5.
11. Wear resistance of switches:
a) the total number of cycles is 16,000.
b) number of cycles of VO under load:
- switches for rated current 80 A 10000.
- switches for rated current 160 A 8000.
12. Overall dimensions (width x height x depth), mm 112x320x157.
13. Weight (stationary version), not more than, 8.2 kg. With electromagnetic drive - 11.9 kg
