Product Description

This range of SPDs are characterised by an 8/20μs current wave, they can prevent the spread of overvoltages in electrical installations and protects equipment connected to it. These surge protector must be replaced if the indicator turns red. They comply with BS EN61643-11.

 

WSA SA Power surge suppressor  is a device used to protect the power system from surge voltage. When a surge voltage occurs in the power grid, it can react quickly and suppress the surge current.
