| Long specification | Surge protection plug for use in connection with the base element VSPC BASE 2SL FG for two wires with a common ground. Two-stage protection circuit in the plug consisting of coarse protection, decoupling resistors and fine protection between the signal wires and the signal ground/ground/earth. Suitable for intrinsically safe powered signal cables EX ia. Version: mechanical identification of the plug to the base element according to the switching type and rated voltage. Protected plug with coding pin and counter-profile for the base element. Optical identification of the protected plug based on the type of protected switching and the voltage level. It is possible to mark the plug. |
| Short specification | Surge protection plugs for base element VSPC BASE 2SL FG, coarse and fine common mode voltage protection for two wires with a common signal ground for intrinsically safe signal cables EX ia. Version: 24 V AC |
