We've been supplying these for solar installations for a while now, and the YM2Z series is pretty much the workhorse for DC protection up to 1500V—you're looking at 16A through 1250A depending on your array size, and we typically stock the 3P and 4P configurations most often. Breaking capasity sits between 8kA and 15kA, which is usually fine for commercial rooftop or ground-mount setups, though if you're pushing into high-fault environments you might want to confirm that spec against your system's short-circuit current.
One thing buyers always ask is about the electrical life, and it's rated above 8000 operations—that's better than many standard MCCBs for DC, and the mechanicla life goes beyond 2000 cycles, so it holds up well for frequent switching in combiner boxes or battery banks. The operating temperature range is -5°C to +40°C, but storage can handle -25°C to +70°C, which matters if you're shipping to a site with extreme conditions.
Actually, we usually recommend the C-curve characteristic for solar appliction because of that it handles the inrush from inverters without nuisance tripping, and it's compliant with IEC60947-2 and GB14048.2—CE, CB, CCC, and ISO9001 certifications are in place, so you're covered for most internaional projects. The arc-extinguishing medium is air, which keeps maintenance straightforward compared to oil or gas-filled units.
What it does is mount directly onto a standard 35mm DIN rail, so installation is quick, and IP20 protection degree means it's fine for indoor enclosures but not for direct exposure to dust or moisture—you'll want a weatherproof box if it's outdoors. One detail that's easy to overlook: the maximum altitude is 2000m, so if your site is above that, derating may be needed, and our company can help with that data on request.
For ordering, our company offer OEM service on these—custom labeling, terminal markings, or packaging—and the MOQ is typically 50 units or so, depending on the pole count and current rating. Lead time is usually 20-25 working days for standdard specs, but we keep some common sizes like 250A or 630A in stock, so check with us on availability.
Yes, the YM2Z series supports 4P up to 1500V DC and 1250A max. Just confirm your exact DC voltage and current specs when ordering so we match the breaking capacity accordingly.
For OEM customizations, the MOQ typically starts at 100 units per spec. If you need a smaller batch for testing, we can discuss a sample order first.
Yes, we include copies of the CE, CB, CCC, and ISO9001 certificates with every shipment. If you need specific test reports for your project audit, just request them in advance.
Standard lead time is around 20-25 working days for OEM orders. Custom packaging or labeling may add a few days depending on complexity.
No, the YM2Z is rated for altitudes up to 2000m max. For higher elevations, derating applies and we'd recommend discussing your site conditions with our engineer for a suitable alternative.
Zippy delivery was the first thing that impressed me. The order arrived far sooner than the initial estimate, which was a fantastic start. The packaging was exceptionally secure and professional, ensuring the product was in pristine condition upon arrival. Regarding the item itself, the build quality feels robust and substantial, exactly as one would hope for a critical protection component. The finish is clean, and the specifications marked on the unit are clear and accurate.
