We've been running these through the full test rig before shiping—overload curve checks at 1250A, short-circuit trip timing, works—and each unit gets a stamped COA with the batch data if you need it.
The housing is flame-retardant, and the contacts are silver-plated copper, which holds up better than standerd brass in high-cycle environments. 3 poles or 4, you choose, but the 4-pole version is what most buyers go with for three-phase four-wire systems. Most of what we stock is fixed install, electric operation, so it’s not for manual switching in the field—just so you know.
And the protection functions cover over-votage, under-voltage, phase loss, overcurrent, and short-circuit—basically everything you'd expect from an 800V insulation-rated unit at 400V working voltage. We don't retest every single unit unless you request it (usually adds 2-3 days), but we keep a sample form each production batch for 6 months in case of a dispute.
It's a compact design for 1250A—about 30% smaller footprint than older equivalents—but the lightning protection is actually built into the arc chamber, not just a sticker on the side. We've shipped maybe 200 or so this year, and the only returns were from people who wired it wrong on teh phase sequence.
Anyway, the GB14048.2 compliance is on every CE and RoHS cert we issue, and our company can provide the test reports for the specific voltage and current ranges you're running.
We can start with a MOQ of 10 units for standard orders, but we’re flexible for larger projects if you need more. Just let us know your volume.
For stock items, lead time is around 7 to 15 working days. Customized orders or larger quantities may take 20 to 30 days, depending on specs.
Yes, it’s fully certified with CE and RoHS, and it complies with GB14048.2 standards. We can provide the documentation if you need it.
Absolutely, we offer both 3-pole and 4-pole versions. You can specify which one you need, and we’ll adjust the unit accordingly.
The silver-plated copper contacts give better conductivity and resist corrosion, which means longer life and reliable performance under high current loads.
