The SUN2000L is embedded with a residual current monitoring unit (RCMU). Only a
single-phase circuit breaker or a similar AC load breaking device is required to function as
the external AC switch (shown by G in
safely disconnected from the power grid.
If the external AC switch can perform earth leakage protection, the rated leakage action
current should be greater than or equal to 100 mA.
If multiple SUN2000Ls connect to the general residual current device (RCD) through their
respective external AC switches, the rated leakage action current of the general RCD
should be greater than or equal to the number of SUN2000Ls multiplied by 100 mA.
A knife switch cannot be used as an AC switch.
