  • Multi-foot TS35/TS32
  • Touch-safe to VBG 4
  • Dual function, disconnect & test

Product description

Test-disconnect terminals are mostly used in the sectors of electricity generation and supply.They are tailored to the variety of switching
demands for current-converter secondary circuits that predominate in these sectors. Current transformers must always have a secondary
circuit when electricity meters and measuring instruments are being replaced, or when making comparative measurements.

CONTA-CLIP test-disconnect terminals are available in the following three basic versions, each with or without a pre-assembled socket plug.
All versions provide touch-safe protection according to DGUV-3.

A captive, screw-on sliding partition is used to separate the current and voltage paths.

The switch position is always easy to detect since the disconnect screw has a yellow insulating sleeve.


In all versions, the STB 14/4 socket plugs can be used for a test pick-off for measuring values using the PS 4 test plug or the conventional (4 mm) insulated test plugs.


The VH 19 connecting sleeves and the BS 25 screws or STB 14/4 socket plugs are required for fastening the QVS cross-switches above the terminal block. The cross-switches  are available from 2 to 4 poles.

The QSB internal cross-switches are positioned within the terminal block and make contact over the sliding contact on the LT- or QT-terminals. The cross-switches are available from 2 to 4 poles.

The BS 25 mounting screws are used together with the VH 19 connecting sleeves to establish contact with the QVS cross-switches.
