Product Description:
Indoor load break switch,whose rated voltae is 12KV.Is adopets SF6 gas extinguishing and insulation medium.It includs three contactors for switching on and switching off.
The phase to phase distance can be 200mm,210mm.
It can protect and control the electric equipment for power supply and transformer substations,especially suitable for ring net cabinet,cable branch cabinet and distribution switch substation.
It complies with standards of GB,IEC.
With its small volume,it is convenient to install and operate.
This load break switch can be used in high altitude.
