Factory Direct SV Series Single Hole Terminals for Circuit Connections

You’re looking at our SV Series single hole terminals, the pre-insulated Y type, and the first thing people notice is that high-conductivity copper core—it’s cold-pressed, which gives it a solid, consistent crimp every time. We run them from -40°C to 105°C, rated at 300V and up to 48A, so they handle most circuit connections without sweating it. The insulation comes in red, blue, or yellow, and that color coding isn’t just for looks—it matches the wire size range, which is 0.5 to 6mm² depending on the model you pick.

Most buyers are in industrial control panels or automotive wiring harnesses, but we also see them in appliance repair shops and small electrical contractors who need reliable crimp for terminal blocks. They’re not really suited for high-vibration environments unless you add a secondary locking mechanism—that’s a limitation we’re upfront about. One thing you’ll appreciate, and it’s something buyers don’t always think to ask, is that the rectangular shape fits standard terminal block slots without rocking, so you get a snug connection the first time.

Anyway, supply-wise, we keep stock on the common sizes—SV1.25 through SV5.5—and the lead time for those is usually 7 days or so. For customiezd orders, like if you need a specific insulation color or a different hole diameter, expect 7 to 20 days, but we can nail that down once we see your spec. MOQ is 1000 pieces per type, which sounds high, but when you factor in the per-unit cost, it’s actually better than reagent-grade alternatives for this application.

Pricing scales with volume, obviously—if you’re ordering 10,000 pieces or more, we drop the unit price by roughly 15-20%, give or take depending on the model. We’ve got CE and ISO9001 certs, and our company can provide the COA if you need it for your inspection. The packging is standerd export packing, so you’ll get them in sealed bags inside a carton, and we usually include a TDS sheet with each shipment.

A detail that comes up a lot: the cold pressing process means the copper doesn’t anneal like it would with hot forming, so you get better tensile strength and less risk of cracking under the crimp tool—that’s something we’ve seen in returns from other supliers. Also, the voltge rating is 300V, but in most cases, you can push it to 350V in dry environments, though I wouldn’t recommend it for continuous use.
