RCD
The Residual Current Device, or RCD, is one of the most important electrical safety devices in both the home and commercial environments.
In short, an RCD protects against injury and death caused by electric shock by detecting an imbalance between the outgoing and incoming total current of a given number of circuits. It works on the very simple principle that if there is a difference in the electricity coming in against that which is going out, then it must have gone somewhere.
This phenomena is commonly known as 'earth leakage' - (or the 'Residual Current' in the RCD's title). It can be caused by a number of problems including poor electrical wiring and DIY accidents such as drilling through a cable when mounting a picture hook or cutting through a cable with the lawn mower. In this type of situation the electricity must go somewhere and choosing the easiest route can travel through the lawnmower or drill to the human holding them to create a circuit and cause electric shock.

What is RCD?

The basic structure of RCD
How do RCD Works - The Power of Electromagnetism
How the RCD Prevents Injury - Milliamps and MillisecondsAn electrical current of just a few milliamps (mA) experienced for just one second is enough to kill most fit, healthy people. RCDs therefore have two key aspects to their operation - the amount of current they allow for Earth Leakage before operating - the mA rating - and the speed with which they operate - the ms rating.
what is the difference of ELE and ELM RCD? The electromagnetic leakage circuit breaker does not require auxiliary power, and there is no circuit board component inside. It has nothing to do with the working voltage of the switch. As long as the leakage current of the line reaches the electromagnetic leakage action current, the leakage circuit breaker will act to cut off the power supply behind it and protect personal safety.
The electronic leakage circuit breaker requires auxiliary power, which comes from the output terminals (load side) of the leakage circuit breaker. It is related to the working voltage of the line. If the voltage is too low, even if there is leakage current in the line and it reaches the leakage current action value of the switch, the switch will not operate.
