Abstract

   AD78S Intelligent electric current relay is our latest researched product on the basis of JL18S DC relay and GL28S AC relay; compared with JL18S and GL28S., it has more function, high setting accuracy and is more convenient to operate.

   AD78S Intelligent electric current relay can be divided into 2 types of AD78S-1 and AD78S-2. It is applied to AC5-5000A and over-current or under-current under DC 5A; AD78S-2 is applied to all the places where need control the over-current or under-current between DC10-10000A.

  This product is widely used in electrical machinery, transformer and the electric transmission line of over-load and short-circuit as a protecting component.
