DEHNconnect RK
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.
End plate for the terminal blocks must be ordered separately!
DEHNconnect RK is a terminal block of 6 mm width with integrated surge
protection and five spring-loaded cage clamp terminals, allowing two
lines to be protected and equipotential bonding with the terminal equipment
to be established. The snap-in fixing at the supporting foot allows
the device to be safely earthed via the DIN rail. To reduce wiring, jumper
bars can be plugged into the protected side of the arrester to transmit
signals. As the enclosure of the arresters is open on one side to minimise
the width, an end plate should be used at the end of every SPD block.
DCO RK
DEHNconnect RK is available in two performance
classes:
DCO RK M:
Surge arrester with energy-coordinated
protection stages
DCO RK E (D):
Surge arrester with diodes only, for
improving the electromagnetic compatibility
(EMC) of terminal equipment
DCO RK accessories
A wide range of accessories such as
jumper bars, labels or end plates make
DCO RK a system easy to operate, which
has been specifically designed for use in
industrial environments.
IP 20
To minimise the width, the enclosure is
open on one side. For protection against
electrical shock, the arrester can be fitted
with an end plate (available as
accessory). If several arresters are
arranged next to one another, one end
plate could be sufficient.

Use of jumper bars
Operating state controls of switch contacts in industrial environments
are frequently fed by a common power source. If several DCO RK
arresters are used, wiring can be reduced by bridging the feeding signal
on the protected side (accessory).
