We've been sending these to industrial plants and commercial building projects for a while now, and the feedback on the ARXM3 holds up pretty well under continuous load.
The 630A frame comes in three breaking capacities—L, M, or H—so you're looking at Icu form 50KA up to 100KA depending on the variant, and Ics is typically 50-75KA which is better than most standard MCCBs for this class.
What you get when ordering is breaker itself with a reinforced BMC base and nylon cover, manual operation only (no motorized option here), and usually the 3P version weighs about 4.8kg while the 4P is a bit heavier at roughly 240mm wide.
Mechanical life is 4000 operations, electricla life is 1000, but for high-cycle applicaion like frequent switching you'd want something with a higher rating—this one's really built for protection, not daily toggling.
We'll send COA with each batch, and the flashover distance is over 100mm so clearance is decent, but confirm your ambient temp stays within -5°C to 55°C or you'll need derating.
Anyway, stock on the 400A and 500A variants is usually available, but the 630A H-type can run 20 days or so if we need to pull from production.
Our MOQ for ARXM3 circuit breakers is typically 10 units per model, but we can adjust for larger or mixed orders—just check with us.
Yes, we include ISO9001 and CCC certification copies with every order, so you have the paperwork for compliance and inspections.
Absolutely, the ARXM3-630L supports 400A and 4 poles—just specify when ordering, and we'll configure it accordingly.
For standard orders, lead time is around 15–20 working days. Larger quantities may take a bit longer, but we'll confirm once we know your volume.
They're designed for indoor use within that range. For outdoor setups, you'd need an additional weatherproof enclosure to protect against moisture and direct sun.
