This surge protector device is developed with thermally protected MOVs that are less in weight and bring more safety. It is protected due to its surge suppression segment which is automated and disconnects when the gadget is introduced to unusual conditions.

They have an inbuilt LED indicator that notifies the users about timely replacements. They are approved by IEC 61643-11/EN 61643-11. They are connected parallel in a circuit. They have a remarkable count of maximum discharge current which is about 10kA. They do not dissipate much power. The ambient temperature lies between -40 to 70°C.

Furthermore, they are reliable and offer endurance.
