Description:

• For use with the base element VSPC BASE 2CL FG for two floating ground-driven paired wires, 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.
• The plug can be marked.
