Max Zs value for AFDD

[Gaz92552]

Does anyone know where I can find the maximum Zs values for AFDD's? Table 41.3 refers to 60898 and 61009-1 but AFDD's are BS 62606

You'll have to check with the manufacturer to be sure but I would expect it to be the same as for an MCB with equivalent tripping characteristic.

It would still be to the type B, C, D trip data. Is it a combined RCBO/AFDD unit? It should be the Zs values given for 61009.

@FlashBangWallop makes a good point, if it is a stand-alone AFDD then it won't have a max Zs value as its not relevant to its operation.

It is a combined RCBO/AFDD so would make sense its rated the same. One of the reasons I was asking is that it didn't auto fill when filling out my test sheet so was second guessing. Ill check with the manufacture and will let people know.

Thanks
