Hager RCBOs deciding not to hold

[Mr.Si]

Just had a hager 32a rcbo go on me today. Nothing wrong with the circuit, i think the internal latching mechanics have broken as it does not hold when disconnected totally and just sitting in my spares box.

Has anyone else had this sort of experience?

It's less than a year old and just in a domestic cu so hasn't exactly been under pressure... Makes me less happy with the brand.

Only active RCDs, the type generally fitted inline with extension leads or supplied as a plugin adapter and a few RCD protected socket outlets or connection units, have a powered hold-on characteristic. This is to prevent unexpected start-up of hand or portable tools after restoration of the interrupted supply.

Interestingly, I had a little fiddle with the RCBO this morning. I managed to get it to work again.
I basically pulled the switch outwards a little toward me and then lifted it up into the on position and it held and now it's consistently holding when I flick it up normally.

Most Odd. Had that with another couple but not as bad. Maybe it was a batch thing.
