We've been shipping these IoT S8002 units for about eighteen months now, and the 16-100A range covers most industrial panel needs — the 6kA breaking capacty is fine for standard distribution, but if you're dealing with high-fault scenarios you'll want to check the short-circuit rating against your upstream transformer specs.

It's basically a 4-pole air breaker with Bluetooth and WiFi built in, so you can trip it remotely via the Tuya Smart app or yell at Alexa to cut power to a specific line, and the timing control function is pretty useful for scheduled load shedding in factories running night shifts.

Overload and short-circuit protection are handled by a thermal-magnetic mechanism (similar to what you'd find in a standard MCCB), but leakage detection adds another layer — most buyers go with the 63A version for general industrial use, and we usually have stock on that rating within 2-3 weeks (check lead time for 100A though, those move slower).

One thing we've noticed is the mechanical life holds up well past the rated 10,000 cycles (we tested a sample to about 13,000 before it started feeling loose), but the electrcial life at 4,000 operations is more of a guideline — if you're switching under full load daily, that number drops faster than the datasheet suggests.

It's not ideal for outdoor panels because of the IP20 rating (dust ingress is fine, but any moisture will kill it), and the operating temperature range of -5°C to +40°C means you can't install it in unheated warehouses in northern climates without addtional enclosure heating.

Anyway, for a fixed-mount 4-pole breaker with CE and CCC certs, the terminal torque spec is 2.5Nm which is standard for 50mm² cables or so, and the pollution degree 2 classification means it's fine for most industrial environments as long as you're not in a cement plant or chemical processing area.
MOQ is 50 units per model, and typical lead time is 15–20 working days after order confirmation. Larger orders may reduce the per-unit cost slightly.
If the WiFi or Bluetooth connection is lost, the breaker still functions as a standard manual unit—you can flip it by hand. The smart features just won't update until the link is restored.
Yes, we can share both CE and CCC certification documents upon request. Just ask your sales contact and we'll email you the PDFs.
Each of the 4 poles handles up to 100A at 380V, with a 6kA breaking capacity. That's the same across the 16–100A range.
Keep them in a dry place between -25°C and +70°C, with humidity below 95% non-condensing. The original packaging is fine for storage up to two years.
