The conditions for ground fault protection by the cercuit breakers are as follows: The requirements
of EN 60364-4-41 are met under these conditions.
For TT systems, please comply with the local laws and regulations of the country or region where
the servo system is installed and used. The rated sensitivity current and loop impedance of the earth
leakage breaker are specified in some cases. The type B ELCB may be specified.
