The LCA-G is an extensible 12-24 kV AIS for the GLBS SF6 LBS. It is used on secondary distribution systems where switching demands are stringent and space limitations are severe. The load break switch is capable of breaking overload currents of up to 2600A at 12kV, while the fuse-combination provides protection from short-circuit currents of up to 31.5 kA at 12kV. Compatible with all other panels of the LCA series, it is also compatible with the IV2000(VCB).

General features include :

Nominal current until 630A.
Max breaking capacity 31.5kA,
S.C withstand capability at (rms) 20 kA/2sec

Panel Dimensions (WXDXH) :

12kV: 375X1000X1850 mm
17.5kV: 450X1000X1950 mm
24kV: 550X1100X2050 mm
