Certain design of terminal blocks e.g. stud type and bus bar terminal blocks where the contacts of the terminal do not form fully shrouded assemblies and hence live parts remain open posing an electric shock hazard. As a safeguard against this, protective covers are used which provide protection against electric shock hazard.

elmex offers various types of protection covers ranging from covering a single terminal block to entire stack of terminal blocks. As an innovative solution to shroud the entire stack of terminal blocks of different height and width, elmex offers protection cover type PCK3 which is mounted on support plate type UHDD. Support plate UHDD is mounted on DIN rail at both ends of the stack and protection cover is snap fit on the same.
