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 – whether direct at the

facilities, near eld or far eld – can cause signal interference

or even destroy connected devices. They could even lead

to an explosion within hazardous areas applications. The

VARITECTOR SSC EX product line, with a width of 12.4 mm,

offers protection against these risks. These products comply

with the new IEC 61643-21 standard. They full the “over-

stress mode” described. They are also in compliance with

the most current ATEX Standard, 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

Lightning and surge protection for intrinsically safe circuits

in the explosion hazard area

No limitations when used in the EX zone

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.

Space-saving

A compact installation is possible because of

the VSSC EX module's terminal design and

12.4 mm alignment width.
