GE GL 310 F3/4031 P/VR User Manual

INSPECTION AND MAINTENANCE
68 OI 248 (EN) REV6 /REV3
The arcing contacts will exhibit wear due to the switching of normal
and short-circuit currents. The effective value of the short-circuit
breaking current is used to evaluate wear.
Reconditioning is necessary after 2,500 operations at rated normal
current or after a specific total breaking current (see figure) has
been reached.
Under certain operating conditions, such as operation of reactors
and capacitor banks (especially back-to-back conditions),
reconditioning will be necessary after fewer operations.
Special approval by GE is required for service under these condi-
tions.
