Advantages of the VARIO® MOVs
The VARIO® range includes a wide range of solutions designed to protect power lines, phone lines and IT systems.
- Great quality/price ratio
- Minor space requirements
- Modular versions for DIN rail configurations
The VARIO® SPDs range is based on two traditional technologies. On the one hand, spark-gaps used in installations equipped with lightning rods or when a high discharge level is required. On the other hand, MOVs whose specificity is to become conductive once a certain voltage level is reached thus evacuating overvoltage surges to the ground.
A leakage current can appear after repeated use. For this reason, installing a thermal disconnector (fuse) or a fault interrupter is mandatory.
