(residual current device and an electronic circuit breaker)

I think you might mean ELCB which is an earth leakage circuit breaker. An ELCB is similar to an RCD, it operates by monitoring the earth circuit to detect any current leaking through the earth due to a fault in the electrical system.
An RCD monitors the current flowing through the live and neutral wires(in a single phase electrical system), if the current differs but a few milliamps for more than 25 milliseconds, it will break the curcuit.

Residual Current Breaker (RCB) works on the assumption that the current going to the electronics device must come out from the neutral wire, if there is no other way for current flow. In simple words, RCB measures the current going inside the connected device and coming out from the device. If both of these current are equal, then there would no problem with the normal functionality of the device.
This device is also known as Current Operated ELCB.
This device is more sensitive and accurate than ELCB and its functionality does not (entirely) depend on the earthed rode wire connection like voltage ELCB.
ELCB stands for “Earth Leakage Circuit Breaker” and it is used for protecting a person from electric shock and injury. The needs of these devices arise because of the number increasing in injuries as well as deaths because of electric shock. This device is invented almost 50 years ago, but nowadays ELCB is not suitable because of its some disadvantages hence another device RCB (Residual circuit breaker) or RCD (Residual Current Devices) whose functionality is same with more advantages, but theory of operation is entirely different from ELCB.

rcd will trip if there is live leakage to earth ,ecb is modern version of fuse

rcd's monitor current so any leakage to earth (fault) trips the circuit, ecb's are to protect against overcurrent so fuseboard doesn't melt during fault.

Atheism: a million. The doctrine or perception that there is not any God or a lack of perception contained in the existence of God or gods - Godlessness. Theism: 2. The doctrine or perception contained in the existence of a God or gods - non secular perception.

Rcd - Is probably a fuse - like the old screw in type -
