1. Basic information

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 same volume

• Fully RoHS compliant – More environmentally friendly

 

It is one of the most used electronic components in electrical vehicles and charging piles for switching and controlling the DC circuits and the equipment. It has long life, high reliability, small size, low power consumption, electromagnetic compatibility, flame retardancy and fast response.

4, Application considerations

 

When the contactor is connected by one or more conductive copper bars, please ensure that the conductive copper bars are closely connected with the contact end surfaces (multiple copper bars need to ensure that the conductive copper bars with large current are closest to the contact end surfaces, followed by the conductive copper bars with small current), and then the flat washers, spring washers and nuts. Improper connection sequence can cause severe overheating.
