           Cautions of Power Relay:

               1.Tips of CZPT Anti-dust Go over

               We very suggest go over :
               (1)When the ambient humidity is ≥ 60% (for example fridge or some place like Indian), the metal components of relay will be weakened in distinct degrees
               due to long-term exposure to the outdoors in conditions of electrical conductivity and services daily life.
               (2)When the dust density is substantial in the surroundings, all varieties of impurities carried in the dust (this sort of as gravel), if gravel is embedded between contacts.
               Firstly, it will impact the typical opening and closing of contactsSecondly, component of the silicon oxide can be employed as a semiconductor to carry out electric power,
               and then the relay’s on and off will are unsuccessful if no anti-dust cover.
              (3)When corrosive gases are critical in the environment, it will accelerate the metallic aging, drastically influencing the service daily life of electrical relays.
               * When none of the above situations exists, the plastic anti-dust go over is not necessary owing to further expense.

              two.Suggestions of Contacts
              (one)We need to shell out attention to stop make contact with motion, adhesion, abnormal use, enhance of contact resistance and other fault phenomena while utilizing.

              (two)The material of power relay can be AgCd571,AgSn08,AgSnOlnO and so forth.Wanjia star manufacturer relay adopted AgSnO2  with higher high quality & stable performance.  
              (three)The mechanical provider life and electrical services existence can be main element as well

              * In a word, great gadget need great relay to reduced the repairing prices and enhance the stamina.
