Manual reset: Normally closed state, after tripping due to overtemperature or unstable voltage, power needs to be manually restored by pressing the reset bar.
Auto reset: Similar to manual reset in basic functionality, after tripping and cutting off power, it detects the water tank temperature, and automatically restores power when the temperature drops to around 30°C without requiring the reset bar to be pressed or disassembling the device.

Note: "15A/16A/20A all interchangeable" means that the device is capable of handling a maximum current of 15A, 16A, or 20A interchangeably.

There are four wires in total, two of which come from the power supply. The brown/red wire connects to "1" and the blue wire connects to "3". The other two wires are connected to the water heater, the red wire to "4" and the blue wire to "2".

 "1" is the neutral input, "2" is the neutral output, "3" is the energised input and "4" is the energised output.
