This device is quite skilled in guarding the electric circuits against voltage spikes by tackling voltage over a threshold voltage.  They hold the most innovative Metal Oxide Varistors in a multi-pole configuration for thermal stability with a LED indicator. They are connected parallelly in a circuitry. These devices are backed by IEC 61643-11/EN 61643-11 certifications and standards. The maximum current discharge offered by these gizmos is 10kA. 

Their ambient temperature lies within -40 to 70°C. They protect electric installations from lightning strokes. They testify to protect the sensitive appliances notwithstanding the exposure risk. Likewise, they are tested independently and are backed by engineering and mechanical support.
