Overview
Switching relays are used in residential, non-residential and
industrial buildings for the purpose of contact multiplication.
They can be used with safe isolation between coil voltage and
contact. Switching relays for direct voltages in particular find
increasing use.
With the 5TE9 100 and 5TE9 101 busbar, the switching relays
can be mounted quickly and safely, e.g. by bus-mounting the
N-conductor and/or infeed
–
and this applies to the whole range
of switching relays.
■
Benefits
•
Fast and simple installation thanks to bus-mounting
•
Switching position indicator when checking the plant for
enhanced safety
•
Manual intervention possible at any time – easy fault locating
due to manual operation.
