WDYK RCBO POW 10A 2P is a 2-pole (1P+1N) smart Residual Current Operated Circuit Breaker (RCBO), which controls the live and neutral wires at the same time, equipped with Wi-Fi and support for eWeLink cloud and eWeLink app. It supports max. 10A. The max. performance is configurable, so you may set any lower values to turn off at. 

But it is not just a circuit breaker though, as it has a power metering / energy monitoring capability, so it also can be used to measure power consumption. It also features a built-in OPS feature (overload-protection system), to protects the connected devices for overvoltage, overcurrent and overpower.

What is the difference between an MCB and RCBO?

MCB cannot protect against earth faults, while the RCBOs can protect against electric shocks and earth faults, too. MCBs monitor the current flow and interrupt circuits during short circuits and overload. In contrast, RCBOs monitor the current flow through the line and return flow in the neutral line. Also, the RCBOs can interrupt the circuit during earth leakage, short circuit, and overcurrent.

RCBO can protect against earth leakage currents, short circuits, and overcurrent, while MCB only offers protection against short circuits and overcurrent. 

This device needs Live and Neutral on the input side and has Live and Neutral on the output side, too. Using the eWeLink app, one may turn ON / OFF the breaker via Internet and iOS (Apple) or Android smartphone App, and also one can set scheduled turning ON / OFFs. The device has a physical button too, similarly to traditional breakers. Its ON/OFF button has a motor inside, so you can remotely turn it on of off. Share remote control in the App with others is also supported. 

Features real-time power metering, daily and monthly statistics are displayed in the mobile app. It also supports downloading the consumption data to your smartphone in CSV format. The smart switch relay provides help not only in remote and scheduled turning ON / OFF ideal solution to understand and optimize your power consumption too.

It meters not only actual power consumption, but also shows actual voltage and current data on the screen. It has OPS (overload protection setting) available (with minimum power, maximum power, maximum current and maximum voltage settings). 100 days of consumption data history export is supported to smartphone from eWeLink cloud in CSV format.
