High voltage DC contactor is a key safety device for new energy vehicles, it’s hermetically sealed and gas filled. Compare with traditional DC contactors/relays, high voltage DC contactor works in circuit voltage greater than 200V, which is much higher than the traditional car 12-48V. It requires the manufacturers to be more professional with high technology and complex production process.

Due to the differences in parameters of new energy vehicle OEMs and models, high voltage DC contactors will be more demanding on small batches, multi-category, and cost reduction. But most famous manufactures mainly produce standard parts at high price.

In my today’s post, I will list some well-known DC contactor manufactures like TE, Panasonic, GIGAVAC, LSIS, Albright, etc. The quality performance of these reputed suppliers is stable and the clients with whom they work are famous like Tesla.

Of course, there are also some Chinese manufacturers providing cost-effective DC contactors, whose products are tested against TE or Panasonic models, perfect replacement with the same parameters and performance, but at a much lower price.

So now, many buyers are willing to look for cost-effective DC suppliers in China who can accept OEM & ODM service, MOQ is very flexible and negotiable, and delivery time is very fast, basically 2-4 weeks.

Let’s see the major players in high voltage DC contactor markets, the advantages and disadvantages of their products, this report will help to find your best high voltage DC contactors partner for your applications.
