I've seen Hager units here multi labled in French, German and English

RCB, FI, Differential

Siemens Ireland seems to have always had its own labeling though. The details on the old RCD are

Siemens - Made in Germany
Current Operated Earth Leakage Circuit Breaker
30mA
60A
Diagram of the circuit and test instructions explaining how to find an earth leakage fault by unplugging all appliances connected to the sockets, resetting the breaker and plugging them back in one by one.
Calling an electrician / having the faulty appliance professionally repaired or disposed of.

Other than that there's a 2 pole RCBO for the shower and 10A RCBO covering lighting in the bathroom and outdoors. (Modern ABB units, much smaller than the old siemens one)
