Many test objects can be connected via a power plug that the operator inserts into the test socket on the connection box. The various test sockets are configured on a per-order basis to meet specific requirements.
We offer a selection of standard junction boxes in various designs, and we also custom-manufacture the appropriate wiring for your specific application.
To connect exposed wire ends, the junction boxes are additionally equipped with quick-connect terminals, which are wired in parallel with the test socket, for example.
Since some country-specific test sockets are not suitable for the full high voltage of 6 kV, the test sockets can be bypassed using jumper plugs. In addition, SCHLEICH also supplies specially manufactured high-voltage-rated test sockets rated up to 6 kV.
It is also possible to connect test leads to 4 mm female connectors for specific measurement purposes.
