EIC "rated time delay" value for a 61008 type-s

psychicwarrior

good day folks

 

out of interest, if anyone has filled in the “rated time delay” entry on an EIC for a 61008 type-s RCD main switch,  what was the value  (presuming the standard has a set value/range)  used and where from ?

 

regards

Habs

    I wonder if that box was intended for the likes of big boy's RCDs - earth leakage relays or add-on modules for MCCBs - that can have a definite (and likely constant) delay time. 

    S-types are just meant to be selective with instantaneous RCDs so often have a delay that varies with the residual current - so there is no one number you can sensibly write down.

    I'd almost be tempted to write “S-type” and cross out the "ms".
