Medium voltage disconnector switch Driescher 12 kV & 24 kV
DRIESCHER Indoor Switch-disconnector H 27
• 3-pole
• Rated voltage 12 kV and 24 kV
• Ratec current 630 A
For frontpanel mounting or mounting besiede with or without actuating.
All switches are generally equipped with quick make and quick break operating mechanism.
The switches are designed for normal operating conditions according to DIN VDE 0670, Part 1000, class Minus 5° Indoor.
The peak value of the ambient temperature is 40O C; the average value over 24 hours is 35° C at best.
The values of the insulating power are related to sealevel.
Reduction in insulating capacity at hights up to 1000 m are negligible due to the decreasing insulating capacity of the air.
