DEHNconnect RK Ex (i)
Terminal block with integrated surge protection
Two-pole terminal block of 6 mm width with integrated surge protection
and cage clamp terminal. Earthing via DIN rail or terminal.
DEHNconnect RK MD EX is a terminal block of
6 mm width with integrated surge protection for
intrinsically safe circuits. The five cage clamp terminals
protect two lines each and additional
equipotential bonding with terminal equipment
can be established. The snap-in fixing mechanism
at the supporting foot of the base part
allows the arrester to be safely earthed via the
DIN rail. As the enclosure of the arrester is open
to one side to minimise the width, it is advisable
to use an end plate at the end of each terminal
block.
