June 16, 20223 yr Hi there, A few days ago I was trying to diagnose some nuisance tripping of an ELU/RCB and it got me considering the use of individual RCBO's, even given their usual premium price. I know that in the UK the use of RCBO's is commonplace now, on basically all circuits in a DB. It seems a smart move, considering how here in SA we usually only see one ELU in a DB, for a whole bank of breakers. Then yesterday I happened across these Swan "ADL9-32" RCBO's. I have seen Swan breakers before, but haven't used them, nor had I seen these particular units. I figure/figured the quality would be similar to the other, shall we say, off-brand breaker brands (like ACDC, etc.), but I also fully expected their price to be astronomical and/or they to simply be a rarity out of the catalogue. Well, I see they range in price from about R160 to R220 for the 10, 16, 20 and 32A versions it comes in, and Mantech has them in stock. It seems Swan and Mantech are from the same holding company, hence them stocking them. But that price seems almost too good to be true. They use 1 din space, so I'm thinking they probably only break one conductor, not both? Not sure how else they would fit the ELU portion and the Overload portion into such a tiny space, and even have them rated at 4.5kA. Anyone have any experience with these things? Or any other Swan brand breakers? I've attached the stock catalogue photo of the C20.
