So I tested the shunt trip on the QOM2200VH1021 while out here in April.

Yesterday, we wired everything up and discovered that "He's dead,, Jim." No connectivity between the 2 shunt-trip wires.

SquareD tells me that while QO breakers [unlike the Home line..] have a lifetime warranty, but a QOMain has a 18 month warranty, from the date code on the label.

My client will not be pleased at the replacement co$t of $600+.
 
I never heard of lifetime warranty on any such product.

Same breaker is used as a main breaker in both QO and HOM product lines.

I don't know about the shunt trip if it would be treated any differently. I also don't know if that particular shunt trip is able to handle constant voltage to the trip coil or not, if not and you are applying constant voltage when you do utilize that feature - probably no warranty.

If this is within the first year of initial install and it never worked to begin with, maybe they will work with you, even if manufacture date is a little older. You may have to keep on them though.
 
Square D has had a lifetime warranty on some residential products for maybe 20 years.

The same products would have 18 months warranty when used in commercial and industrial applications. The warranty starts on the date of manufacture, so it allows for a typical 6 months for the product to sit on shelves while still allowing a contractor to provide a 12 month warranty to most end users.

They are probably not unique among manufacturers.
