I did find the technical manual for the device but couldn't find any information about it's operation (admittedly I only skimmed it).

Some devices need to have the actuator moved to the off position before they can be turned back on, but if you can't do that then I'd say there is a good chance it has failed mechanically and should be replaced by a suitably qualified person.

Is it fitted with under voltage release or shunt trip?

accidentally trip off, but it could not be reset. it is out of stock in uk

Is it fitted with under voltage release or shunt trip?

Should they stop it from being moved to the Off/Reset position?

 

[wei zeng]

can not reset under no power

 

[wei zeng]

yes, it stopped in middle of position between off and on. how to deal the problem

 

[Antony1]

if it has undervoltage release fitted it won't reset if there is no voltage

Look carefully for a very small screwhole, insert small screwdriver and turn in or out. This will release the switch. That is my theory. As some MCCB have an adjustor for setting the trip sensitivity. I think this may be the case, obviously not sure as I am not there.

Hi, Vortigern
Many thanks for your theory. It worked for me as well. one small screwdriver inserted one hole and turned out, then the switch worked as normal. Thanks again, other wise it cost £1040 to replace and waiting for two month shipping from states.
