We're looking at your RFQ for the 800A 3P, and the ARXM3-800A-3300 is what we'd propose for that high-breaking-capacity need — it'll handle 75kA at 400V and still give you 30kA at 690V, which is better than most standard MCCBs for that voltage range.
The mechancial life is rated at 2500 operations, but realistically, the electrical life is where you'll feel limit at 500 operations (usually 2-4 weeks of heavy cycling), so this isn't suited for frequent switching application like motor starters.
It's about 9.55kg per unit, and the dimensions are 210.5 by 281 by 159mm, so it fits most standdard panel layouts without needing extra space. We typically ship these in single-piece cartons with foam inserts, and the MOQ is 10 units for stock orders.
One thing buyers don't always ask about is the flashover distance — it's ≥100mm here, which is tighter than some alternatives, but it passes CCC and ISO9001 certification without issue. Also, the arc-extinguishing medium is air, so no gas handling concerns.
You'll get a COA with each batch, usually within 3-5 working days after order confirmation, and our company can provide the test report for the 75kA breaking capacity if your engineer needs it for the project spec. Lead time is roughly 20 days or so for a standard 50-unit order.
Anyway, the manual operation type is standard for this model, and we don't offer an electric version for this partciular variant. If you need 4-pole or 630A, our company have those too, but confirm the exact model before we quote.
Our MOQ for this model is 10 units for standard orders. If you need fewer, we can check stock availability, but lead times may vary.
Yes, the ARXM3-800A-3300 is CCC and ISO9001 certified. We can provide copies of the certificates upon request before purchase.
For a quantity of 50 units, lead time is usually 15-20 working days. If you need it faster, we can expedite for an additional fee.
No, this model is fixed at 75kA Icu at 400V and 30kA at 690V. For other breaking capacities, we’d recommend checking our ARXM4 or ARXM2 series instead.
Store it in a dry, clean place with temperatures between -25°C and 55°C, and avoid direct sunlight or moisture. Keep the packaging sealed until you’re ready to install.
