We needed something that could handle DC voltages up to 1000V for our solar string combiner boxes, and the 10kA breaking capacty gives us enough headroom for most fault scenarios we've seen in the field — the C-type trip curve is pretty much standard for this kind of load anyway.
It's availble in 1P through 4P configurations, so for a typical 2-pole string you grab the 36mm unit, and the 18mm per pole width means we can pack more circuits into a small cabinet than with some bulkier alternatives we've tested before.
Mechancial life is rated at 20,000 operations but electrical life drops to 4,000, which is typical for air arc extinguishing breakers in DC service — you wouldn't use this for frequent switching, it's really a protection device not a disconnect switch you cycle daily.
The current range goes from 6A up to 80A, and we usually order the 63A units for main feeders while the 10A or 16A ones work for individual panel strings, but you'll want to double-check ambient temperture range of -5°C to +40°C if your gear sits in direct sunlight.
CE and CB certified plus it meets GB/T14048.2 and IEC6947-2, so compliance paperwork is straightforward, and the DIN rail mount saves installation time — basically a drop-in replacement for our existing panels without rework.
One thing that caught my eye is the storage temperature goes down to -25°C, which matters for our warehouse in winter, and the 4-pole 72mm version handles the 80A rating better than some 2-pole units we tried before.
You can choose from 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, or 80A. Just pick the one that matches your load.
It's certified with CE, CB, and CCC, so it meets international safety and performance standards for most markets.
Yes, it's rated for DC voltages up to 1000V. Just make sure you select the right pole configuration—higher voltages typically need more poles.
Our MOQ is 100 pieces per model and rating. We can discuss smaller quantities if you're testing samples.
Lead time is usually 15-20 working days after order confirmation and payment. For urgent orders, we can sometimes expedite.
