Remote boards need a breaker that already measures and talks. WTB2-80ML reports current, voltage, leakage and temperature over 4G or WiFi.
Replace a plain MCB with WTB2-80ML when the site must be read and opened remotely.
The 2P device is AC 230V, In 32/40/50/63/80A, B/C/D curves, 6kA, IΔn 30/50/100/300mA.
It monitors current, voltage, leakage, energy, frequency and temperature.
WTB2-80ML 4G uses RS-485, Bluetooth and 4G.
The WiFi version uses RS-485, Bluetooth and WiFi.
Ambient -25 to +65°C, humidity ≤95%, altitude ≤2000m.
Pair with WTXU-03 on three-phase incoming and Q3R-63 if the site has a generator.
Unmanned rooms still need overload, leakage and a way to open the circuit from the office.
WTB2-80ML 2P, AC 230V, 32-80A, 6kA, B/C/D. Residual 30/50/100/300mA. Wiring up to 25mm². Mechanical life 20,000; electrical life 10,000.
WTB2-80ML is 2P / 230V. On a three-phase riser keep WTXU-03 (true RMS, 45-65Hz) for phase loss, then feed single-phase ways into WTB2-80ML.
Q3R-63 4P ATS for generator changeover. WTSP-A40 on the AC incoming so a surge does not take out the smart breaker electronics.
Smart MCB plus the voltage relay, ATS and SPD that sit around it.

Use it as the 230V way that must be metered and opened remotely.
WTB2-80ML 2P, pick 32-80A and B/C/D from the load. 4G if there is no LAN; WiFi if the site already has it.
Remote open/close plus leakage 30-300mA. Ambient down to -25°C is inside the listed range.
WTXU-03 on the incoming, WTB2-80ML on each 230V outgoing.
Q3R-63 ATS upstream. Put the smart breaker on the load side that you still need to meter after transfer.
