RCD Identification

[21P]

I am working in the middle east and have been asked by my customer to inspect the electrical here. The problem is that he has asked me to make sure that the RCD breakers that are supposed to be installed are there. I have looked online at pictures and all I have been able to determine is that it should have RCD or RCCD writen on the front of the breakers. The breakers they have installed are all SEZ equipment. Not the gretaest website to research on. Is there any other way to identify these breakers? Am I correct on the writing that should be on the front of the breaker?

If they where using American Standard Square D equipment this would not be a problem. But they aren't and it is.

Any guidence you guys can give me would be greatly appericiated.

Thanks in advance.

Possible markings are likely to be RCD, RCCB, or maybe RCBO if it is a combined MCB & RCD. RCCD is a new one to me.

Every RCD I've seen has a test button on the front; I've never seen an MCB with one. That's probably the easiest way to spot them. Other than that there is probably something like [Δ]I 0.030 or [Δ]I 30mA marked, or a different current if so specc'd.

If we learn from our mistakes I'm getting a great education!
