Needed to spec something for a mixed-load distribution board where we're combining lighting, small motors, and some office equiment under a single DIN-rail assembly, and the SG65LE-63 came up as a pretty standdard fit for that—rated 230/400V AC, 6kA breaking, 6A up to 63A, but the real deal is the 30mA residual current integrated into a compact unit.
What it does is bundle overload, short circuit, and earth leakage protection into one module, so you're not stacking separate RCDs and MCBs on every circuit, and with B, C, or D trip curves avaliable we can match it to load type without guessing—most buyers go with C curve for general distribution, but you'll want B for sensitive electronic loads.
Mechanical life is rated at 10,000 operations, which is decent for this class, though in practice for a commerical panel you'll probably never cycle it that many times—the PA66 housing is flame-retardant and holds up fine at IP20, so no issues in clean indoor environments, but it's not suited for wet areas or outdoor enclosures unless you add a proper gland.
The trip mechanism uses a zero-sequence current transformer internally, which picks up imbalances pretty reliably at 30mA residual (usually 2-4 weeks lead on the custom amperages), and we've had consistent COAs from the supplier backing the IEC60898 and GB16917.1 marks—CE and CCC are fine for our domestic installs, but check your local regs if exporting.
Anyway, pricing per unit comes in roughly 30% less than equivalent ABB or Siemens stock, and MOQ is 50 pieces or so for a mixed pole batch (1P+N, 2P, 3P, 3P+N, 4P options), so our company can cover a small building run without overcommitting—spec sheets are with my procurement file if you want to double-check teh operating temp range of -5°C to +40°C.
You can get it in 1P+N, 2P, 3P, 3P+N, and 4P configurations. So whether you need single-phase or three-phase protection with neutral switching, there's a version for your setup.
Yes, it holds CE, CB, ISO9001, and CCC certifications, and it's built to IEC60898 and GB16917.1 standards. That means it's accepted in most markets globally.
Our standard MOQ is 100 pieces per model, but we can be flexible for smaller trial orders if you're just testing the product. Just reach out to confirm.
Absolutely. It comes in Type B, C, or D trip curves, so you can match it to your load type—like resistive, inductive, or motor starting loads.
It ships in standard export cartons, with each unit individually boxed. Store it in a dry, ventilated area between -5°C and +40°C, away from direct sunlight and moisture.
