What is the Regular Preventive Maintenance to be carried on NSX breaker

There are three recommended maintenance levels.
The table below indicates maintenance operations and their intervals according to the level:

Provided all the environmental conditions are more favorable, maintenance intervals can be longer (for example, Level III maintenance can be carried out every 3 years).
If just one of the conditions is more severe, maintenance must be carried out more frequently (for advice contact Schneider Electric Services).
Functions linked specifically to safety require particular intervals.
NOTE: It is advisable to test operation of the remote electrical stop commands and the earth leakage protection (Vigi module) at regular intervals (every 6 months).
