The test system is composed by a draw-out adapter module, which supports 12 front test receptacles and 12 rear contact plugs, a drow-out blind module as a cover, and a fixed mount counterbase.
The modules composing the test system have their dimensions corresponding to the protection relays of DENOVA series, with flush, rack or projecting mounting.
