TOTAL SYSTEM PROTECTION
Lightning Transient Overvoltage Protection for Mains Power
All mains power lines entering or leaving the building are prime routes for lightning and switching induced surges and overvoltages to enter the electrical and electronic systems. Due to the large cross sectional area of these cables high current and voltage surges can enter with minimal attenuation.
By fitting Wallis Surge Protection devices in parallel with the incoming mains, surges and overvoltages can be reduced to an acceptable level. Protection devices are available for single and three phase as well as three phase split busbar systems.
