LKE'S air insulated LBS panels are designated LCA for L(LBS panel)-C(Cable incoming/outgoing) A(Air insulated).

If a LCA unit air load break switch, it is further designated LCA-A, and if it houses a gas load break switch it is designated LCA-G, finally if it houses a vacuum load break switch it is designated LCA-V.

LCA panels are all indoor systems which are extendable so they can be combined to build larger distribution switchboards or ring main units (RMUs).

Further more, LCA-A, LCA-G and LCA-V can be combined in series or parallel connection to build a whole switch board system. This allows for more economical solutions where smaller loads are protected by switches with lower breaking capacity whereas higher loads are protected by switches with higher breaking capacity.

Panels housing LK-LBS are commonly used as incoming units or as isolator units.

The LK-LBS/fuse combination is used usually as transformer protection units for transformers of ratings less than 800 kVA.

The diagrams on the right represent some of the possible arrangements within the LCA-A.

The LK-LCA housing the LK-VLBS will protect transformers up to a rating of 5000 kVA. With the LK-VLBS, the panel must be equipped with surge arrested to protect against over-voltages.

Furthermore the LK-LCA-V panels are equipped with current protection relays for overload and short circuit protection.
