High Current 50PE UL94 V0 Screw Type Grounding Terminal Blocks for Power Distribution

It's a screw-type grounding block that clamps down on your copper wire for power distribution, nothing fancy—we build these for the EU and UK markets where the standard are tight. Basically, you run a stripped conductor between 16 and 50mm² into the contact, tighten brass screw, and it's a solid, low-resistance ground path for high current application.

Votage rating sits at 500V with a current handling of 17.5A, but what it does is handle those chunky cables—6 AWG up to 0 AWG—with the soft cable range starting at 25mm², which is what most installers actually use anyway. Teh housing is nylon PA66 with a UL94 V0 flammability rating, so it won't propagate a flame if something shorts, and the operating temp range is -40°C to +105°C (pretty generous for most panel environments).

Mounts onto standard NS32 or NS35 DIN rails, which is the usual setup in European cabinets—we see these a lot in building management and factory floor distribution. The standard color is that yellow/green grounding combo so it's immidiately obvious when you're wiring a panel full of black and blue terminals.

We've got TUV, CE, UL, VDE, and CCC certs on file, so you're not chasing down import paperwork for the US or EU—COAs are included with each batch, and the SGS report covers the latest compliance. MOQ is typically 50 pieces for the 1-position version, but if you need multiple positions (up to 10 on a single block), it's usually the same lead time.

is the IP20 rating—it's not for wet environments, so don't mount this where condensation or water splash is a factor without an enclosure. Mechancial life is rated at 1000 connection cycles or so, which is better than the cheap terminals you'll find online but still expect screw creep if you overtighten (stick to the torque spec in the datasheet).

Lead times from our warhouse in Zhongshan run about 20 working days for a standard order of 500 units, but we keep about 2,000 pieces in stock for the 50mm² version at any time—check before ordering if you need faster. Pricing breaks below 100 units are pretty flat, but once you hit 500, it's roughly 30% less per piece (depends on the Customs code paperwork, so get a proforma first).
