Customizable ASKW1 Series Air Circuit Breakers with Intelligent Protection Functions

We've got decent stock on the ASKW1 series right now, roughly 200 units or so in the 2000A to 4000A frame sizes, but the 6300A typically takes about 3-4 weeks for delivrey once you confirm the order. The standard controllers—the L type with LED and the M type with LCD—are usually on the shelf, though the H type with communication capability may need an extra 10 business days depending on order volume. Actually, most buyers go with the M type for the display clarity, and it's a solid workhorse for most setups.

What it does is it gives you overload, short circuit, and undervoltage protection in one package, so you don't need separate devices for each function. The impulse withstand voltage is 12kV, which is better than many entry-level breakers for this class, meaning it handles transient surges without tripping unnecessarily. But just a heads-up: it's electric operation only, so it's not suited for manual-reset scenarios where you'd want a mechanicla override—that's just how these are built, no way around it.

Certifications are CE, CCC, and ISO9001, so compliance with most industiral sites is pretty straightforward. We usually provide a COA with each batch, though you should confirm lead time if you need it with HPLC data or the full TDS, as that can add a day or two. The arc extinguishing medium is air, and it's a 4-pole unit in your configuration, which handles the neutral line nicely for 3P+N setups—saves wiring hassle.

For shipping, we pack each breaker on a wooden pallet with foam inserts, wrapped tight, so damage in transit is rare. The fixed version is easier to handle for standdard panels, while the drawout type gives you faster maintenance access, but it costs a bit more and adds about 5% to the weight. Check with us if you need a custom lead time for the 6300A variant though, as demand fluctuates a lot.
