Runs at 1000V DC with the 2-pole setup, and you’re looking at 63, 100, or 125 amp options depending on your load — the BCD trip curve handles the coordination, and instantaneous tripping kicks in at 20 times the rated current, which is pretty standard for solar combiner boxes or string-level protection, but don’t expect it to work for AC circuits or high-humidity environments without extra sealing since it’s only IP20.
We usually have stock on the 63A and 100A versions, about 50 units or so, but the 125A can take 20 days or so to ship (check lead time for bulk). The flashover distance is at least 50mm, which matters when you’re wiring multiple breakers in a panel — spacing gets tight, so that spec is worth noting before you mount it.
Most buyers go with the 100A for standdard PV arrays, and teh manual operation is fine for field disconnects, but you’ll need to pair it with a proper DC isolator if your system requires remote tripping. It’s rated form -25°C to +50°C, so it actually handles cold better than some competing models that struggle below -10°C.
Certifications include CE, CB, CCC, VDE, and ISO9001 — that CE and VDE combo usually satisfies European installers without extra paperwork. The dimensoins are 145 by 170 by 110mm, so it fits most DIN-rail enclosures, but the white housing does show dirt faster than black units if that matters visually.
Our MOQ for the GZM1-PV is typically 10 pieces per rating, but we can flex a bit on mixed orders. Reach out to confirm stock on the 125A variant.
Yes, we hold CB, CCC, and ISO9001 certifications for this model, and we can share a copy of the DC1000V flashover test report showing ≥50mm clearance on request.
With 20ln, a 63A breaker trips instantly at 1260A. That's designed to handle high inrush from PV inverters while still protecting against short circuits.
We can adjust the trip curve, but it requires a custom batch order with a minimum of 500 units. Standard stock ships with the BCD curve as listed.
Store it in a dry place between -30°C and +60°C. The operating range is -25°C to +50°C, but storage can handle a bit more temperature swing.
