We've got these in boxes of 45 pieces, and the 3W8H-30A model is what you're looking at here—it handles 30 amps at 400 volts, with a 16mm2 wire section, and the ceramic shell is pretty much main draw for high-heat situations where plastic would just melt.
Basically, it's a push-pull connection for quick wiring, and you weld the contacts on for a secure termination, so it's better than screw-type blocks in tight spaces or vibrating setups.
The brass contacts are what carry the current, and the ceramic housing gives you that insulation and heat resistance—most buyers go with these for industrial cable wiring in ovens or machinery, but they're not great for outdoor use without extra protection.
Lead time is usually 20 days or so for whlosale orders, and we typically have stock, but confirm before ordering if you need a rush—teh MOQ is one box (45 pieces) or our company can do custom quantities if you ask.
Also, the hole count is three, which is standard for three-phase connections, and the rectangular shape makes it easy to mount on DIN rails or panels—just keep in mind the 400V rating is for general environments, not high-votage specialty stuff.
Our standard MOQ is 100 boxes, but we can sometimes negotiate smaller quantities for first-time orders. Just reach out to our sales team to discuss.
Yes, we provide a certificate of conformity and can share test reports for the brass contacts and ceramic shell on request. Just let us know what documentation you need.
Absolutely, the 16mm² wire section is well within spec for 30A at 400V. The brass contacts and ceramic shell ensure reliable performance under those loads.
They come in boxes of 45 pieces. Store them in a dry, cool place away from direct sunlight to keep the ceramic and brass in good shape.
Yes, the contact termination is designed for standard welding or soldering processes. The brass contacts accept solder easily for a secure connection.
