We've had customers running older 11kV ring main units where the existing oil breakers just couldn't keep up with fault levels anymore, and that's exactly the kind of spot this thing solves—dropping in as a fixed vacuum unit that handles the arc without any oil maintenance headaches.
1250A continuous with 11kV, 22kV, or 33kV votage taps, the M2 mechanical life and E2 electricla endurance basically mean you're not swapping this out every other year, and the CE and CCC certs cover most regulatory boxes without extra paperwork.
It works fine for conventional overcurrent and OVP duties, but honestly, it's overkill for basic low-voltage panels—you'd want something simpler there—and the fixed installation type means you can't just yank it for portable testing without unbolting whole thing.
3-pole, electric operation, export wooden case included with the order, and our company can customize the mounting flange if your substation layout is a bit off—just give us the hole pattern.
Most buyers go with teh 22kV option for standard distribution, but the 33kV variant handles worst-case surges better if your grid's flaky on the primary side.
Lead time is usually 20 days or so from order, give or take a few depending on whether we've got the exact model in stock—check before committing to a tight schedule.
This breaker comes in three voltage ratings: 11kV, 22kV, and 33kV. You can pick whichever matches your distribution system.
We typically require a minimum order of 10 units per voltage rating, but we can discuss smaller quantities for trial orders or special projects.
Absolutely. We can share digital copies of our ISO9001-2000, CE, and CCC certificates right away. Just let us know which one you need.
M2 means the breaker is tested to handle at least 10,000 mechanical operations without maintenance. That's standard for high voltage applications where reliability is key.
It ships in an export standard wooden case, fully secured to prevent movement. We've used this packaging for years with no damage issues, even on ocean freight.
