DACN10S-L AC surge protector is used for the 'secondary' protection of the single-phase networks against the surge voltages creating by lightning. Unlike the DACN10S, the DACN10S-L incorporates an in-line safety disconnection and double output connection. The DACN10S-L provides common and differential mode protection and features an LED colour change from green to red at end of life. The DACN10S-L surge protector series is a single module DINRail mounted device designed to be installed close to the equipment being protected; it will normally be connected ‘downstream’ of a Type 1/2 'primary' surge protector.
