Tongou TO-Q-SY2-JZT Testing with the IoT Portal Hub

We test the over current and over voltage cut-out on the Tongou high current switch and circuit breaker. We also inadvertently demonstrated the problem with feeding it with too low a rated fuse! This was connected to the IoT Portal Zigbee hub which was the device used to send the SMS/email messages and make the phone calls.
