DIN rail or surface mounted test interface

The SAX is a surface-mount test block that ensures secure and reliable interfacing between substation devices, such as protection relays, fault recorders, revenue meters, and a diverse range of components within the system side of the power grid. Notably, the SAX serves a dual purpose by functioning as both a terminal block and a test block. This allows for space and wire savings within the panel, as well as optimization in design.

The PAX is a meticulously designed test plug specifically tailored to match the precise configuration of the SAX test blocks. Upon insertion into the corresponding test block, the PAX adeptly isolates the substation devices from the system side equipment. This isolation serves the crucial purpose of safeguarding the substation devices while simultaneously facilitating seamless connectivity to test equipment. As a result, the PAX enables the execution of secondary injection tests with ease and precision.
