factory Outlets for Voltage Spike Suppressor - 36 Sidall Structure Voltage switching type ac lightning surge protector（8/20μs） – Leihao

When the thunderstorm season is coming, lightning protection is particularly important at this time. Lightning enters the room through power lines or other ways, causing damage to people and equipment; LEIHAO Lightning Protection Company has many excellent lightning protection products, of which the surge protector of power supply is an important part. Now we will briefly introduce the parameters and uses of a first-class surge protector.

(1) in the front end of the main power switch in the floor distribution box, LH-50I 4P is generally used as the primary protection of power supply;

② LH-50I 4P should also be used at the low voltage end of transformer and the front end of main power switch.
③ When the distribution box is independent outdoors, LH-50I 4P should also be used as the primary power protection.Equipment connected to AC power supply network is easily affected by many electrical problems that may be expected in unstable operation, which leads to equipment failure, life reduction and even damage. LH-15I series surge protectors are designed to meet the protection requirements of all low-voltage devices for industrial lightning surge.  The product range of this series is classified by product type and power supply category (AC or DC).
