Going off your RFQ, we’re looking at the ASKW1 series, which is a frame-type universal circuit breaker rated from 2000A up to 6300A for 400V and 690V systems—the high breaking capacity hits 85kA, and that 12kV impulse withstand votage is standard. Most buyers go with the drawout version for easier maintenance, but fixed is fine if you’re not swapping it out often.
The controller comes in L, M, or H variants, basically LED display, LCD, or full communication-ready. You’ll get overload and short-circuit protection out of the box, but the L type doesn’t have adjustable curves, so if you need that, go with the M or H. It’s designed for air arc extinction, so no oil or gas to deal with, and the black housing is pretty much what you’d expect for a substation panel.
3P, 4P, or 3P+N poles are available, though we typically see 4P for most industrial feeds. Short-time withstand current is 65kA for 1 second, and mechanicla life is 10,000 cycles while electrical life is about half that—roughly 5,000—but that depends on what current you’re actually breaking. Altitude should stay under 2000 meters or you’ll need to derate the temperature range (which is -5°C to +40°C anyway).
Power loss varies by model, somewhere between 40 and 800W, so factor that into your enclosure cooling if you’re stacking several. CE and CCC are current, and ISO9001 applies to our production line—COAs are included with each unit, and we usually have stock for the 2000A and 3200A frames, but the 6300A might need a lead time of 8 weeks or so. Communication protocols are optional, so specify Modbus or Profibus if you need it.
One thing buyers occasionally miss is that this isn’t suited for DC applicaion or low-voltage residential panels—it’s strictly AC, and it’s pretty bulky for anything under 800A. The remote trip coil is an add-on, not standard, and the LCD controller interface can be a bit clunky compared to newer touchscreen units, but it’s reliable once programmed.
Anyway, if you can confirm the frame current, pole count, and whether you want fixed or drawout, we’ll send the quotation and the shipment details inside 2 business days usually—MOQ is one unit, but bulk pricing drops at 10 pieces or so.
It goes up to 85kA at 400V. That's the high end, so you'll get solid short-circuit protection for most industrial setups.
Yes, the ASKW1 comes in both fixed and drawout versions. Drawout makes swapping or servicing the breaker a lot faster without rewiring.
The H-type controller offers optional communication protocols—typically Modbus RTU or Profibus, but you'd need to confirm the exact option with us when ordering.
Yes, the ASKW1 is CE, CCC, and ISO9001 certified. We can provide copies of the certificates with your shipment.
Our MOQ is usually 2 units for the ASKW1 series, but it can vary by model and stock. For the 4000A frame, we typically have them ready within 15-20 working days.
