We needed reliable 2-pole DC MCB for our solar array combiner boxes, and the 20A rated current at 1000V DC was exactly what the system design called for — the GDDC1-63-C20-2P-1000V handles overload, short circuit, and overvoltage protection without needing separate components for each function.
Breaking capacity at 6000A is more than adequate for our residential installations, but honestly, most commerical guys I know also go with this same unit because the 1000V rating gives them headroom for series-string configurations, and the IP20 protection class is fine for indoor distribution boxes (just keep it out of direct weather).
What it does is fit neatly into a standard DIN rail panel at 36mm width per pole, so the total footprint is 72mm for the 2-pole version, and the fixed insallation method means no rattling or loose connections once you torque it down — a detail that matters when you're commissioning 50 units at a time.
Certifications came through as ISO9001, CE, CB, and RoHS, which satisfied our compliance team without any pushback, and the applicable standard IEC 60898-1 is what most local inspectors expect to see on the paperwork anyway.
Lead time was about 3 weeks or so from order placement, and we ordered 200 units to hit MOQ threshold — the suplier typically stocks these in batches of 500, but they pulled from production for our quantity, so confirm stock if you need less than 100 pieces.
Not ideal for AC systems, obviously, since it's specifically a DC-rated breaker with arc extinction designed for direct current, so don't try swapping it into an AC panel — the arc-quenching characteristics are completely different and you'll get nuisance tripping or worse.
It's rated for 1000V DC, so it's built for high-voltage solar arrays, not standard household AC circuits.
Yes, it covers overload, short circuit, and overvoltage protection. The 6000A breaking capacity handles serious fault currents in solar installations.
It's certified with ISO9001, CE, CB, and RoHS, so it meets safety and quality standards for most global markets, including EU and many Asian regions.
Typical lead time is 15-25 days depending on quantity. MOQ is usually 100 pieces, but we can discuss smaller trial orders for first-time buyers.
IP20 means it's protected against solid objects larger than 12.5mm, like fingers, but not water. Install it inside a weatherproof enclosure if outdoors, like a combiner box.
