EVC DC square contactor uses highly reliable ceramic sealing technology. Compared with traditional DC contactors, this product series has: 

• Complete sealing – The contacts are in a sealed environment with low contact resistance and good stability, which can be used in harsh environments. 

• Filling gas – Filling in the arc extinguishing gas to improve the arc extinguishing performance of the product and prevent the contacts from oxidation.

• Magnetic blow-out – Use permanent magnets to blow and pull the arc, increasing the capacity of arc extinguishing. 

• Miniaturization – New technology increases the load capacity of the same volume 

• Fully RoHS compliant – More environmentally friendly It is one of the most used electronic components in electric vehicles and charging

It is one of the most used electronic components in electric vehicles and charging piles for switching and controlling the DC circuits and the equipment. 

It has a long life, high reliability, small size, low power consumption, electromagnetic compatibility, flame retardancy, and fast response.
