ELCB Trip Current

07/03/2009 1:03 PM

I have an ELCB. There is a label on it which says, 30mA 20mS.

I know that 30mA is the maximum tripping current but what does the 20mS mean? Is it important?

Probably the tripping duration time - 20 milliseconds.

Earth Leakage Circuit Breaker

the time has to be operating time.

Since in the specifications that is the only one with time as unit.

The 20mS is the maximum time that the leakage current must exceed 30mA before it trips. It might trip sooner than that, but it will not trip later than that.
