Current reverse-phase detection models:
Voltage reverse-phase detection models:
No abnormality develops when 20 times the set current value is applied for 2 s, 2 times with a 1-
minute interval.
No abnormality develops when 1.15 times the relay’s rated voltage is applied once for 3 hours.
No malfunction occurs when pulse containing 100% of the 2nd to 9th harmonics is applied (open-
phase switch set to “Low”). (See note.)
