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.

The 5TE9 100 and 5TE9 101 busbars enable fast and safe mounting of the switching relays, e. g. by bus-mounting the N conductor and/or infeed.

Note:
Busbars to match the 5TT4 2 switching relays can be found under: Switching devices ––> Busbar systems.
