The LCA-V is an AIS for the IVISAF vacuum switch. It is used for heavy duty switching solutions that exceed the capabilities of other types of switches. The LCA-V is capable of 10,000 electrical operations at nominal current and will break short-circuit currents of up to 20kA at 12kV, while the fuse-combination provides short-circuit protection up to 31.5 kA at 12 kV ratings. Using short-circuit protection relays, fuses or both simultaneously, the LCA-V offers a wide range of protection possibilities for the user.Compatible with all other panels of the LCA series, it is also compatible with the IV2000(VCB).
