At Weidmüller, new solutions for the energy sector
are developed according to local or application-based
installation requirements.
In some countries, control and protection of switching
installations for transmission and distribution networks
must comply with the EA-TS 50-18 standard. The
standard prescribes "spring-loaded" terminals in
conjunction with hook-blade cable lugs in order to
ensure additional safety. The Weidmüller "spring-loaded"
terminals of the WDU SL series and the disconnect
terminals of the WTL SL series comply with this standard.
In the SL versions, the clamping yoke is backed up by a
helical spring. Furthermore, this arrangement permits two
conductors to be connected to one terminal when the
hook-blade cable lugs are placed back to back. The aim of
this arrangement is to ensure good electrical contact even
if someone forgets to tighten the clamping screw!
