Actually, we've been shipping these ARM6DC units for large-scale solar arrays over the past few years, and one thing I can tell you is that the 1500V DC rating really does matter for modern PV strings that run at higher voltages—most residential setups sit at 1000V, but if you're spec'ing for a utility-scale system, this gives you the headroom you'll eventually need. The 4-pole configuration handles both positive and negative conductors on ungrounded arrays, so you're covered for both poles of the DC circuit, but don't use it for standerd AC distribution boards because of that it's really not designed for that—it's a DC-specific device through and through.
What you're looking at is a 250A frame with a 63A to 250A adjustable rating range, which means you can dial in the trip setting to match your string combiner or inverter DC side without swapping hardware, and we typically keep common sizes like 160A and 200A in stock for quick shipment. The ultimate breaking capacity comes in at 40kA, which sounds high, but for these high-voltage DC systems where arc quenching is literally dangerous, you want that margin—especially if your array is near a substation or transformer where fault currents can spike.
Between us, mechanical endurance is only 7,000 operations, which is about 3,000 fewer than some other breakers you probably compared this against, but for a fixed instalation inside a combiner box—where it's set and forget—that number really isn't a problem, and the electrical endurance of 1,000 operations is actually generous for a DC breaker (the current is DC, which is brutal on contacts). The compact dimensions—142mm wide by 200mm tall, with a slim 108mm depth on the compact version—fit nicely in most combiner cabinets, though you should double-check your busbar spacing before ordering since the terminal layout varies by manufacturer.
We've supplied these through ISO9001 and CCC-certified channels for about four years now, and our batch records show that over 90% of the units pass a full hipot test at 12kV impulse withstand—though I'd still confirm with the COA when yours ships, just to be safe (usually 2-4 weeks lead time). One thing buyers rarely ask about but definitely should: the screw terminals are M8 stainless steel, so if you're using alumnum lugs in your DC circuit—a common practice—you need anti-oxidation paste because galvanic corrosion is a real issue at these voltage levels.
Anyway, with a price point that's roughly 15-20% below European equivalents for the same 40kA/1500V rating, most buyers go with this as the default for new PV arrays over, say, a 500A frame they don't really need—but I'd still say the 20kA service breaking capacity is why you've got proper coordination with downstream fuses. That's basically it for the numbers, though our company can adjust the trip curve if your inverter manufacturer specifies a tighter tolerance than standard.
We typically require an MOQ of 10 units for this MCCB. If you need fewer, just reach out—we can sometimes flex on that for first-time orders.
Standard lead time is about 15-20 working days after order confirmation and payment. Stocked models might ship within a week.
Yes, it's certified under both ISO9001-2000 and CCC. We can provide copies of the certificates with your shipment.
Icu is 40kA—the max short-circuit current it can handle once without damage. Ics is 20kA, meaning it can safely break that current and still be used afterwards.
Absolutely. We can set the trip rating to any value between 63A and 250A. Just specify when placing the order.
