Thanks for the replies, Johno - that helps to know it was apparently only US made ones that went bad. Trumpy - thanks for the pic, they do appear to be "standard" DIN rail ones you have. The ones I was concerned about are exactly like the US ones with the StabLok connection, hopefully we got them made in a factory with better quality control. I'll try and get some pics next time I'm on that job.
