Middle cover plates
Each type of RSA terminal blocks is also optionally available with end and middle cover plates in twelve colour variations (except the RSA 70 A terminal, which is encapsulated). The cover plates are made of polyamide PA 6 with V0 flammability according to UL 94. The end cover plates are used to close off the terminals and protect the live parts. When it is necessary to separate two adjacent terminals and extend the air gap between the living parts due to the nature of the application, the middle cover plate is used.
