Rmu Accessories 12kv Lbs 630A/1250A Load Break Switch
Product Description
The two-position/three-position load break switch is commonly used in fully enclosed combined electrical appliances (GIS) or composite electrical appliances and is not a separate product. Commonly used in XGN ring network cabinets. The so-called three stations refer to three working positions: 1 closing position where the main disconnect of the disconnector is connected, 2 isolated positions where the main disconnect is separated, and 3 grounding position on the ground side. The three-position switch actually integrates the functions of the isolating switch and the grounding switch and is completed by a rotary blade structure.

Applicable conditions
Altitude: ≤2000m;
Ambient air temperature: -45ºC~+50ºC;
Relative humidity: daily average ≤95%, monthly average ≤90%;
It is not suitable for installations where there are frequent and severe vibrations, water vapor, gas, chemical corrosive deposits, salt spray, dust and dirt, and fire and explosion hazard installations that obviously affect the performance of the mechanism.
The rated SF6 gas pressure is 0.04MPa, and the SF6 gas meets the requirements of GB/T 12022-2014 "Industrial SF6″.
