SIRIUS 3RT2 contactors/contactor assemblies
2.6 Connection
Solder pin connection
For applications where the contactors are to be soldered onto a PCB directly, a solder pin
adapter is available for SIRIUS size S00 contactors up to 5.5 kW or 12 A.
Devices with a solder pin connection have the following properties:
● The terminals are suitable for a 1-conductor connection.
● All connections can be accessed from the front and are clearly arranged.
● A maximum of 2 conductors with a cross-section of 0.25 mm
used at each connection point.

2-conductor connection
2 conductor ends can be connected to every main, auxiliary, and control circuit connection.
These connections are also suitable for untreated conductors, which may have varying
cross-sections. This connection system offers numerous benefits, including laying the
foundations for problem-free looping through and parallel connection without intermediate
terminals.
