What to do if Eaton Circuit breaker does not trip?
If your Eaton Circuit breaker doesn't trip, the possible reasons are: there's no control power, or the voltage is out of range; a fuse might be blown or the switch is off, or the wrong voltage is applied; the secondary disconnect might not be connected. Check these potential issues to resolve the problem.
Why Eaton Circuit breaker closing-spring charged but breaker does not close?
If the closing spring is charged but your Eaton Circuit breaker doesn't close, it could be due to several reasons: there's no control power, or the voltage is out of range; a fuse might be blown or the switch is off, or the wrong voltage is applied; the secondary disconnects are not in service; the anti-pumping device is in service; there's a shunt closing release failure; or the breaker is between service and test position when it's in the switchgear. Investigate these possibilities to find the cause.
