VARITECTOR SSC EX

When used in intrinsically safe circuits within EX zones 2 to 0, the VARITECTOR SSC can reliably protect measurement and control signals from lightning and surge voltages.

Lightning and surge voltages, coupled from the field side to machines and facilities, can cause signal interference or even destroy connected devices. They could even lead to an explosion with high risk Ex zone applications. The new VARITECTOR SSC EX product line, with a width of 6 mm, offers protection against these risks. These products comply with the new product standards of IEC 61643-21:2008. They fulfil the "over-stress mode" described there. They are also in compliance with the most current ATEX standards in EN 60079. Lightning and surge protection components are versatile and simple to use since they feature direct contact to the PE, many marking and diagnostic options, and an easily disconnected signal path. The VARITECTOR SSC EX takes advantages of these features so that it can easily be used in place of a transfer terminal.

VARITECTOR SSC EX

Features:

The Ex zone approval provides the proof that the VSSC EX can be used in all Ex zones (from zone 2 to zone 0) for dust or gas.

A compact installation is possible because of the VSSC EX module's terminal design and 6.2-mm alignment width.

Versatile labelling: labels for equipment and individual connections, also easy to read SnapMark markers for any installation position

The VSSC EX prevents compensation currents via the PE. It also complies with the over stress mode of the IEC 61643-21:2008 product standard.

Because of the negligible Li and Ci values, no special proof is required for Ex zone use.

The VARITECTOR SSC line protects measurement and control signals and comes in a 6.2-mm width. Electronics functions are combined with features such as cross connections, markability, and a high connection density. This terminal design lightning and surge voltage protection solution can replace individual terminals in the electrical cabinet and free up space on the mounting rail.
