Stuck protection trip alarms
Hi All
I have a Masterpact MTZ breaker which is showing a long term and short term protection trip.
The breaker is currently on load , I suspect there is a manual switch stuck or loose behind the main casing . Its would be helpful to not have to isolate the breaker. Is there any solution to clear this fault?
