5.2.7.5 Earth Leakage Relay Unit

Sensing the earth leakage current, the unit (relay) send a signal To the

3-phase and the 1-phase breaker to trip-off in order to shut-off The circuit

to the terminals (loads).

(refer to.7-3 Earth Leakage Relay Unit and Grounding)

5.2.7.6 Amp Meter Changeover Switch

Using this switch, the current between the phases (R.S.T) will be

displayed on the Amp meter.
