Important note

Product information
Mode 2: State where the voltage-limiting part of the SPD was short-circuited due to a very low impedance within the SPD. The line is inoperable, but the measuring equipment is still protected by means of a short-circuit.

Tender specification sheets

Long specification
Surge protection plug for use in connection with the base element VSPC BASE 1 CL R for one floating-ground driven paired cable with integrated status display and remote monitoring option. Two-stage protection circuit consisting of coarse protection, decoupling resistors and fine protection between the signal wires and coarse common mode voltage protection to earth. Mechanical identification of the plug to the base element according to the switching type and rated voltage. Optical identification of the protected plug based on the type of protected switching and the voltage level. Protected plug with coding pin and counter-profile for the base element. It is possible to mark the plug. 
Short specification
Surge protection plug for base element VSPC BASE 1 CL R with integrated status display and remote monitoring option. Transverse voltage coarse and fine protection of one floating-ground powered paired cable, coarse common mode voltage protection to earth. Version: 24 V DC
