Description:

• For use with the base element VSPC BASE 1CL FG for a single floating ground-driven paired cable, utilize a surge protection plug.
• For use in intrinsically safe Ex IA circuits, a two-stage protection circuit with coarse protection, decoupling resistors, fine protection between the signal wires, and coarse common mode voltage protection to earth is provided.
• The rated voltage and switching type are used to mechanically identify the plug from the base element.
• Optical identification of the protected plug according to voltage level and protected switching type.
• A counter-profile and coding pin-equipped protected plug for the base element.
• One option is to mark the plug.
