You're looking at a unit that needs to handle 12kV and 630A continuous without flinching, and the 20kA breaking capacty means it can clear a serious fault—basically, it's built for outdoor substations or factory yards where reliability matters more than bells and whistles.
The copper-tungsten alloy contacts are what you want for arc erosion resisance, and the SMC insulation does a decent job of keeping phase-to-phase leakage down even when it's been sitting in rain for a week or so; mechanicla life is rated at 10000 operations, which in most cases translates to years of service if you're not cycling it daily.
We usually stock the ZW8-12F variant, but if you need the G or M versions for different mounting or impulse ratings, those are available too—though lead time can stretch to 20 days or so depending on the batch. The spring operating mechanism is pretty much standard here, and the IP54 enclosure handles dust and splashing water, but don't expect it to survive full immersion.
One thing you might not think to check is the altitude limit—it's 2000m, so if your site sits at 2500m, you'll need derating or a different unit entirely. Also, the 42kV/48kV power frequency withstand voltage is solid for most industrial setups, but the 75kV/85kV lightning impulse rating is tighter for areas with frequent storms, so confirm your local requirements.
We can do minor customizations on the terminal layout or the operating mechanism, but it's not a full OEM job; for that, you'd typically need a larger MOQ. The copper-tungsten contacts are better than standard copper for breaking heavy arcs, though they do cost a bit more.
Shipping is via standard freight, and we'll provide COA with each unit—HPLC isn't relevant here, but the ISO9001 certification covers the production process anyway. It's a 1-year warranty on mechanical parts, but the vacuum interrupters usually outlast that by a long shot.
Our MOQ for this breaker is typically 10 units, but we can negotiate smaller quantities for first-time buyers. Mixed batches of models like ZW8-12G or ZW8-12M are no problem, just let us know the breakdown.
Standard lead time is 15-20 working days after order confirmation. If you need it faster, we can prioritize production with a small surcharge — typically cutting it to 7-10 days.
Sure, we include ISO9001 cert with every shipment. For specific test reports on breaking capacity or voltage withstand, we can send them digitally within 2 days of request.
Each breaker is wrapped in moisture-proof film and packed in a wooden crate with foam padding. The IP54 rating means they’re dust-tight and splash-proof, so they handle storage well too.
The mechanism is designed for 12kV, but we can tweak the spring tension or add auxiliary contacts for your specific control system. For voltage changes, you’d need a different model — best to check with our tech team.
