TEST plug adaptor modules with Cage Clamp connections have now been added to Wago's 870 series terminal block range.
Distributed through NHP Electrical Engineering Products , these specifically designed multi-pole modular test plug adaptors are fully sealed for protection and are available for the testing of factory wired terminal strips.
The 870 series test plug adaptor is only 5mm wide and matches the dimensions of the 870 series Cage Clamp compact terminal blocks.
Flush installation of the adaptor can be made in the top of the terminal block by taking the place of one of the two available jumper contact positions. Once installed it is still possible to use the remaining position for a single jumper bar if required.
An optional 5mm spacer can be installed along with the test plug adaptor allowing terminal blocks of a different potential in the same series to be skipped. In this way the make up of test plug requirements can be adapted specifically to that of the terminal strip.
For convenience the terminal blocks and test plug adaptors are also equipped with the same marking tag receptacles, enabling the possibility of the addition of marking via Wago's specific marking systems.
