Test disconnect terminals SPTK 6

Test-disconnect terminals are mainly used for power network, electricity generation and supply applications.

They are perfect for the wide variety of switching demands in the current-transformer secondary circuits that are common in these types of applications.

 

Current transformers must always have a closed secondary circuit, for use when electricity meters and measuring instruments are being replaced, or when making comparative measurements.

 

All versions provide touch-safe protection in compliance with 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 STBI 19/4 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.

 

Cross-switches QVSI

The VH 19 connecting sleeves and the BS 25 screws or STB 19/4 L socket plugs are required for fastening the QVSI cross-switches above the terminal block. The cross-switches  are available from 2 to 10 poles.

Cross-switches QSBI

The QSBI 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.

Mounting screw BS 25

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

Switch lock PTK-SP

The PTK-SP switch lock is mounted over the slider on the SPTK terminals. It keeps the partition screws from being accidentally touched by a screwdriver.

Insulated socket plugs STBI 19/4 L

The STBI 19/4 L socket plugs can be screwed into the inside cross-connection channels. They are used together with the VH 19 connecting sleeves to establish contact with the QVSI cross-switches. They are also used to hold the PS 4 test plugs  or conventional (4 mm) insulated test plugs.

Short-circuit plug KS-SQI

The KS-SQI short-circuit plugs are used to make pluggable cross-connections between the SPTK terminals in the outer cross-connection channels. The plugs can also be put in the  built-in park position of the SPTK terminals when not in use.  The short-circuit plugs are available from 2 to 5 poles.

Cross-connector SQI 6

The SQI cross-connector is used to make a pluggable  cross-connection between the SPTK terminals in the outer  cross-connection channels. The cross-connectors can also  be put in the built-in park position of the SPTK terminals  when not in use. The cross-connectors are available from  2 to 30 poles.
