Switches are intended for work in cases of the complete distributing devices (CDD), cameras of stationary unilateral service (KSO) and cases of the complete transformer substations (CTS) internal placements on tension class to 10 kV of three - phase alternating current with a frequency of 50 Hz for systems with the isolated neutral.
Nominal rate of climatic factors in accordance with GOST 15150 - 69 and TOAST 15543 - 73.
At the same time:
— The top working value of air temperature around the switch of - 55 °C (at a temperature over 35 ° the S - rated current decreases by 50% ) taking into account temperature increase in KRP, KSO, KTP;
— The lower value of working air temperature around the switch minus 45 °C;
— Relative humidity of air of 80 percent at a temperature of 20 °C.
The control of the switch and knives of grounding is carried out by means of the PR - 10/250 drive.
