Maintenance schedule
Proper maintenance of the equipment allows good electromechanical operation to be maintained over time.
The maintenance plan for SACE Emax 2 circuit-breakers specifies the maintenance frequency for the different
types of site conditions.
We include the table indicating the frequency with which maintenance should be carried out and the relative
routine maintenance operations required.
Maintenance in standard envi-
ronments
(1)
Maintenance in dusty environments
(dust level measured > 1mg/m3)
Frequency
One year or 2000 operations or after trip
-
ping on short circuit
6 months or 1000 operations or after trip-
ping on short circuit
(1)
See chapter 5 - Environmental conditions on page 21 .
Compliance with the following rules is also recommended:
• Even circuit-breakers that are operated infrequently or that remain closed or open for long periods of time
must be subjected to programmed maintenance.
• All the circuit-breakers provide information on the number of operations performed in the presence of
auxiliary power supply of the Trip Unit. With Ekip Dip releases, the information can be obtained with the
aid of Ekip T&P and a PC on which the Ekip Connect software is installed. With Ekip Touch releases, the
information is available at any time on the appropriate display. With Ekip Dip releases, installation of the
mechanical operation counter is recommended (supplied on request).
• During the service, visually inspect the circuit-breaker from the outside to check for the presence of dust,
dirt or damage.
