We usually quote 45 working days for a standdard 12kV pole-mounted unit at 630A rating, but the 2500A models with 31.5kA breaking capasity can slip to 60 days or so if we're busy — roughly 120 to 180kg depending on the exact combination you pick, and we ship on pallets with full IP54-rated enclosure for outdoor use.
It basically chops the arc in under 60 milliseconds when it opens, which is pretty much instantaneous for the protection scheme upstream, and the spring mechanism lets you operate it without an external power source — just pull the lever and you're set.
42kV power frequency withstand and 75kV lightning impulse, the vacuum interrupter handles full load breaks up to 100 cycles before contact wear becomes a concern, though mechancial life is rated at 10,000 operations give or take — most buyers go with the 1250A variant for distribution feeders because of that it hits the sweet spot between cost and headroom.
What you get when ordering is breaker itself with the spring mechanism pre-installed, a separate control cabinet if you specify it (otherwise it's just terminals), and a COA form the factory verified by third-party HPLC — but the altitude derating above 1000m isn't automatically applied, so confirm if your site sits at 2000m or higher.
It's not suited for indoor substations without an enclosure modification because teh IP54 rating keeps weather out but doesn't address internal condensation at high humidity — we had one buyer try it in a damp basement and the auxiliary contacts corroded within six months.
We offer three breaking capacity options: 20kA, 25kA, and 31.5kA. You can pick whichever matches your system's fault current requirements.
For standard models, our MOQ is 10 units. If you need custom specs or smaller lots, just ask — we can often work something out.
Standard models ship in 4-6 weeks. If you need faster delivery, we can rush it for you within 3 weeks, depending on stock.
Yes, we include copies of both IEC 62271-100 and GB/T 1984 test reports and certificates with every shipment. We can also send them ahead of time if your project requires approval.
Standard rating is up to 1000m altitude, but we can supply a version rated for up to 4000m if you're working at high elevations. Just let us know when ordering.

Came across this 12kV Outdoor High Voltage Vacuum Circuit Breaker while sourcing equipment for a substation upgrade. The ordering process was straightforward, and the initial communication was clear. However, the shipping and logistics experience was quite mixed. The estimated delivery window provided was accurate, which was a positive start. The breaker itself arrived securely packaged on a robust pallet, with no visible external damage to the shipping crate—a testament to good packing practices. Unfortunately, the actual transit time was longer than initially anticipated due to several unexplained delays in the freight carrier’s network. Tracking updates were sporadic and not very detailed, leaving us to guess the shipment’s location for a couple of days. This lack of real-time visibility was frustrating, especially for a critical component with a planned installation date. Upon unboxing, the unit’s build quality appears solid. The external housing and hardware seem robust and suitable for outdoor installation, with a finish that looks like it can withstand harsh weather conditions. The overall craftsmanship from a visual inspection is good, with no obvious defects in the welding or assembly. The documentation included was comprehensive, which is helpful. As for service, the supplier’s post-order support has been responsive. When inquired about the shipping delay, they were prompt in contacting the freight company on our behalf, though they could only relay the information they received. They have been professional in their correspondence. While the product itself seems to meet the basic quality expectations for such hardware, the logistical hiccups and communication gaps during transit were a significant drawback. The experience underscores the importance of reliable logistics partners for heavy electrical equipment. Hopefully, the performance upon installation will align with the initial quality impression.
