Inspection of electrical and
mechanical accessories
Check the accessories:
1. Check that the accessories are securely fixed to the circuit-breaker.
2. Check that the accessories are connected correctly to the circuit-breaker.
3. Make sure that the releases (YU-YO-YC) are in good conditions (absence of excessive
wear, overheating, breakages).
4. Make sure that the mechanical operation counter functions correctly (if present) by
operating the circuit-breaker.
5. Check the wear on the brushes of the gearmotor and if necessary replace them.
NOTE:
You are recommended to change the gearmotor if it has performed more than
10000 spring loading operations.
