           Cautions of Power Relay:

               1.Tips of CZPT Anti-dust Cover

               We hugely suggest go over :
               (one)When the ambient humidity is ≥ sixty% (for instance refrigerator or some nation like Indian), the steel components of relay will be weakened in various degrees
               due to prolonged-phrase exposure to the outdoor in terms of electrical conductivity and support life.
               (two)When the dust density is large in the surroundings, all sorts of impurities carried in the dust (such as gravel), if gravel is embedded between contacts.
               Firstly, it will influence the typical opening and closing of contactsSecondly, part of the silicon oxide can be utilized as a semiconductor to perform electrical power,
               and then the relay’s on and off will are unsuccessful if no anti-dust include.
              (three)When corrosive gases are critical in the surroundings, it will accelerate the metal getting older, greatly affecting the services lifestyle of electrical relays.
               * When none of the earlier mentioned conditions exists, the plastic anti-dust cover is not required due to further value.

              2.Suggestions of Contacts
              (1)We should shell out consideration to avoid get in touch with motion, adhesion, abnormal use, increase of speak to resistance and other fault phenomena although making use of.

              (2)The substance of power relay can be AgCd571,AgSn08,AgSnOlnO etc.Wanjia star manufacturer relay adopted AgSnOtwo  with substantial good quality & stable overall performance.  
              (three)The mechanical provider existence and electrical support existence can be principal aspect as well

              * In a phrase, great gadget need to have great relay to lower the fixing rates and enhance the stamina.
