Subsequent damage after a full short-circuit trip of the circuit breaker
If, after a full short-circuit trip, the circuit breaker is closed again without first checking it, the
drive or the circuit breaker can be subsequently damaged.
● Before reclosing the circuit breaker, carry out a voltage check and measure the resistance.
Provide the results of these measurements to the Service & Support organization. After the
Service & Support organization has checked the values, if necessary replace the vacuum
tubes of the circuit breaker.
Damage caused by incorrect parameter assignment
Malfunctions can occur if you change parameters.
● Do not change the parameters, e.g. for the motor circuit-breaker.
Note
To complement these operating instructions, the List Manual contains an overview of all
parameters as well as a selection of function diagrams to describe the operating principle.
