Amendment 3 compatible device

Newfutile

During an eicr I have come across a wylex wrds  40/2 BS EN 61008 (RCD) Residual Current Device on a board for the solar inverter.

The diagram on the side seems to suggest it has contacts that disconnect the test button.also it does not seem to be marked in/out,line/load or arrows.

Would this mean that it's bi directional?

Also the BS EN 60898 mcb an nhxb20 is this bi directional?

Or should I just contact electrium

    AMD 3 says "Product standards as listed in Appendix 1 for some protective devices, including RCCBs, RCBOs, circuit-breakers and AFDDs, require these devices to be marked to indicate if they are unidirectional e.g. “in” and “out” or “line” and “load” or arrows." - so no markings should indicate indicate that it's bi-directional.

    Or that it complies to an earlier version of the standard that pre-dates the need for such markings.

    Not in this case, as it is very much a current device, but on older parts, beware...

    Makers datasheet here does not mention anything.

    That said I have always found them very helpful if you require a definitive statement
