AP

The AP end plates are normally used at the end of a row of terminals. If different terminals are being used within the same terminal block, then you should insert end plates in order to ensure that the touch safe protection is maintained. The outer dimensions of the end plates match the dimensions of the terminals.
Coloured end plates are used quite often in order to establish a clear visual separation between the different circuits or voltage levels. In addition, the use of end plates increases the clearance and creep-age distances, which in turn influence the voltage ratings.
The locking pegs ensure that the end plates can be mounted quickly.
Because of the special design of the RK series, an end plate does not need to be used to separate neighboring QI cross-connectors of different potentials.
