circuits and tripping.
saTECH TSB-14-P-H/V
The test plug TSP-14-P-H/V includes a guides and a poka-yoke system, to make easier the
insertion into the test block in the proper position and ensuring the opening of all
contacts, of

involuntary extractions, turning the black buttons of the test block.
There are 28 banana plugs in the test plug, which allow the use of safety banana plugs: 14
banana plugs of 4mm are used for the test injection of the relay protection, and the other 14 to
provide access to field elements.
All the banana plugs of the test plug are identified by a number that corresponds to the same
number in the test block.
When the test plug is inserted into the test block, the user should push it until there is no gap
