Actually, once you start handling these TD4-9.4 blocks, you'll notice teh 9.4mm pitch gives you just enough room for solid wiring without eating up all your PCB space—we've shipped thousands to EU buyers who love that balance between density and ease of access.
For 400/690VAC and 25/13.5A nominal current, it's basically plug-and-play for industiral control panels or power distribution, though we don't recommend them for high-vibration environments where a screw-clamp might lock better.
We usually keep MOQ around 500 units or so for stock orders, and the UL 94V-0 PC housing with brass nickel-tin contacts passes most compliance checks we've seen for US and UK imports, plus our company provide the TDS and SDS with every shipment (lead time is typically 20 days form order).
The 5.0kV surge voltge rating and CTI between 250 and 400 mean these hold up decently in damp conditions, but what it does is give you solid insulation class III coverage without the fudginess of cheaper polyamide blocks—you'll want internal wire section limit of 0.5-4.0mm² kept in mind for smaller stranded wires.
Stripping length runs 5-7mm, which is pretty much standerd for pluggable socket connections, and we've seen labs swap these in for test jigs where quick changeovers matter more than ultra-high cycle life.
If you're importing into the US, we've got the documentation for UL recognition and the COA with HPLC purity data; the -40°C to +130°C operating range covers most plant floor conditions without needing special handling, anyway.
Our standard MOQ is 1000 pieces for the TD4-9.4 model. We can negotiate lower quantities for first-time orders or samples.
Lead time is usually 15-20 working days after order confirmation and payment. For urgent orders, we can expedite to 10-12 days with a small surcharge.
Yes, we can provide a CE declaration and UL 94V-0 flammability test reports. The PC insulation material is UL recognized, and we can share the relevant documentation upon request.
We can adjust the stripping length within 5.0-7.0mm, but the wire section range of 0.5-4.0mm² is fixed due to the clamp design. Custom colors for the housing are also available.
Store them in a dry, ventilated area at -25°C to +55°C. Keep them in original packaging to protect against dust and moisture, which can affect the insulation resistance.
My experience with this wholesale order of terminal blocks was primarily positive, with a few areas for note. The logistics were handled quite efficiently. The shipment arrived well within the estimated timeframe, which was crucial for our production schedule. The packaging was secure and professional, with all items clearly labeled and separated by type, making inventory a straightforward process. There were no missing items from our bulk order, which is always a concern with large purchases. The quality of the terminal blocks themselves appears to be solid. They feel robust and well-made, with clean molding on the plastic housings and the metal components showing no signs of corrosion or poor finishing. They snap together and onto the PCB rails with a satisfying, secure fit, which bodes well for long-term reliability in our industrial control panels. The markings for voltage and current ratings are clear and legible. Regarding service, the communication from the manufacturer was prompt and helpful during the ordering process. They confirmed specifications quickly and provided all necessary documentation, including the UL certification details, without needing multiple requests. This level of attentiveness for a wholesale transaction was appreciated. However, while the overall delivery was fast, the tracking information provided was somewhat basic and updated infrequently, causing a bit of uncertainty mid-transit.
