We've been running these through test rigs for a few weeks now, and the SG65-63 series holds up at 10kA breaking capasity across all poles — 1P through 4P. The PA66 nylon housing is flame-retardant, which matters more than most people think when an arc flash happens, and they're up to 63A at 230/400V AC (usually enough for residential panels or small commercial sub-boards). What it does is give you overload and short circuit protection with B, C, or D trip curves, so you're not stuck with one profile for everything.
Most of the people ordering these are either maintenance teams retrofitting older distribution boards or small industrial setups that don't want to pay for Siemens-tier pricing. 2 or 3 batches we tested had slightly different trip times on the D curve compared to the spec sheet, but all fell within the IEC60898 tolerance bands — so it's not perfect, but it's consistent enough. Basically, if you're throwing these into a lighting or motor circuit, the mechanical life of 10,000 operations is fine, but don't use them in high-cycle automation gear.
Each batch comes with a COA from the supplier — we usually have stock, but confirm lead time if you're ordering the 4P 63A variant since those move slower. We tested three lots from different and the trip characteristics varied by maybe 2% on the B curve, so batch consistency is better than reagent grade plastic parts from other vendors I've seen. housing materail is IP20, which means no water resistance, so don't stick these outdoors without an enclosure — that's a real limitation.
Anyway, certifications include CE, CB, CCC, and ISO9001, but we didn't get the specific test lab reports upfront; the COA covers HPLC and general functional checks. Terminal capacity goes up to 25mm², which is handy for wiring larger circuits without crimping adapters. I'd say go with the 10A or 16A options unless you need the 63A for a sub-feed — that's what most buyers pick for standard lighting loads.
Lead time is roughly 20 working days or so, give or take, depending on the quantity — they do a retest policy if you return within 30 days, but we haven't needed it yet. One thing you might not think to check is the operating temperture range of -5°C to +55°C, which is fine for indoor panels but not for freezers or direct sunlight installations.
Our standard MOQ is 100 pieces per model, but we can mix different amp ratings within the same series to reach that number. Just let us know your combination.
Absolutely—we can share the CE, CB, CCC, and ISO9001 docs along with the IEC60898 test report for the 10kA rating. Just request them from your sales rep.
Typically 15-20 working days for that quantity, depending on current production load. We'll confirm a precise schedule once you place the order.
The terminal capacity is up to 25mm², so it'll handle most standard residential and commercial wiring. For larger cables, you may need a reducer.
Yes, all three curves are offered across every pole option (1P to 4P) and all current ratings from 6A to 63A. Just specify the curve when ordering.
