We've seen these go into quite a few large industrial setups, and the 2000A frame is usually the sweet spot for most buyers, though you can go all the way up to 6300A if your load demands it—the ASKW1 series handles that range pretty well, actually, with 3P, 4P, or 3P+N configurations depending on your system.
Breaking capacity hits up to 85kA at 400V, which is decent for most main distribution panels, but it's the short-time withstand of 65kA for 1 second that matters more in selective coordination scenarios, and the impulse withstand sits at 8kV or 12kV depending on your voltge class (typically 690V systems need the higher rating).
You'll want to pick between the controller types: the L model with a basic LED display is fine for simple protection, but the M type adds an LCD screen for local monitoring, and teh H version includes comms capabilities if you're integrating into a BMS—most buyers go with the M or H, honestly, since the cost difference isn't huge.
We usually have stock on the fixed versions in 2000A and 3200A frames, but the drawout type (which is easier for maintenance swaps) might need 20 days or so lead time, especially in 4-pole configurations, and we can provide CE and CCC certs with every unit, plus ISO9001 for the factory quality system.
One thing that trips people up is operating voltage—these are 400V, 660V, or 690V at 50 or 60 Hz, but the breaking capacty drops above 690V, so if you're pushing higher voltages, you'll want to confirm the derating curve with us, as it's not something we always have on hand.
For ordering, we need the frame current, pole count, controller type (L/M/H), and whether you want fixed or drawout—MOQ is typically 2 units for custom combos, but our company can do singles on standard 2000A fixed units, and we'll include a COA with each shipment, though the TDS and SDS are availble upon request.
The MOQ for the ASKW1 series is typically 5 units per frame rating, but we can negotiate for smaller trial orders. Sample units are available for evaluation, though you'd cover the shipping cost.
Standard lead time is 30-45 days from order confirmation, depending on current production load. For the 4000A drawout with H controller, we usually ship within 35 days.
Yes, CE and CCC certificates come with every shipment, along with ISO9001, ISO14001, and ISO45001 docs. We can also email you the type-test report for the 85kA breaking capacity at 400V upon request.
The L controller uses a basic LED display for settings and fault indication. M adds an LCD screen with more detailed data, while H includes the LCD plus built-in communication ports (like Modbus) for remote monitoring.
Store it in a dry, ventilated area between -5°C and 40°C, away from dust and corrosive gases. Each unit comes individually packed in a plywood crate with foam inserts to protect the drawout mechanism and terminals.
