(2) The ultimate breaking capacity of low-voltage circuit breakers should be greater than or equal to the maximum short-circuit current of the circuit. (3) The rated voltage of undervoltage tripper is equal to the rated voltage of the line. (4)The rated current of overcurrent tripper is greater than or equal to the maximum load current of the line.
Answer (1 of 5): At rated current, MCB will not trip whether it is AC or DC current. In one other response, it is said that since at rated current (1 A in the example), in case of AC 230 V the power is 230 W where as in case of DC 24 V it is 24 W hence MCB will not

RCCB is named as Residual current circuit breaker because of it protects against residual current. Residual current means flow of leakage current between live conductor to earth. Current can flow in two different path, one is neutral and another one is earth.
A typical electrical distribution box will include a bus bar, fuse links, switches, bypass equipment, and residual current detector (RSD.). At a broad level these components will aid in: …
