HCDP series Definite Purpose Contactor for HVAC/R application

Design of Product Reliability

Product Highlight：

Coil protective cover design to better protect the iron core;

Damage of Unprotected：

Most of the application scenarios are dusty and the iron core is not protected, which will cause the iron core area to be gray, then affect the product performance;

Product Advantage：

Silver contact point protection treatment ensures long-term low contact resistance and connection reliability;

Influence of Unprotected：

Silver contact point are easy to vulcanize, which affects product contact resistance; no power after action;

Method to realize：

Increasing the cleaning of silver contact point and the high-temperature protection treatment process, extending the vulcanization cycle of silver contact point to make the contact resistance change slowly;

Product Advantage：

AgCdO2 silver contact point, and the uniform thickness of the silver layer ensure the electrical life;
