Parameter Description
Phase angle oset protection The standards of certain countries and regions require that the
device needs to be protected when the phase angle oset of
the power grid three phases exceeds a certain value.
10-minute UV protection Species the 10-minute undervoltage protection threshold.
10-minute UV protection time Species the 10-minute undervoltage protection duration.
10 minute OV protection (V) Species the 10-minute overvoltage protection threshold.
