2.4.6 Earth leakage relay
An earth leakage relay provides protection in case of
an earth leak current. It detects and indicates an earth
fault current and activates the main circuit breaker.
The detection level is set at 30 mA with instantaneous
trip, but it is adjustable in intensity and in trip delay.
2.4.7 Earth pin
The earth pin, to be connected to the ESS’s earth
terminal is located at the bottom of the frame on the
outside.
