The Surge Voltage Protection Unit of Series VSSC ... Ex serves to limit any surge voltages in intrinsically safe
circuits. They are intrinsically safe as per Control Drawing 3 57951.
The earth connection can be made via the mounting foot to a normalized metal mounting rail and via a terminal.
Several units for different intrinsically safe circuits may be mounted next to each other.
Ambient temperature range: -40 °C to +120 °C for temperature class T4,
-40 °C to +85 °C for temperature class T5,
-50 °C to +70 °C for temperature class T6.
Electrical data as per Control Drawing 3 57951.
