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.)
Malfunction: 10 to 55 Hz, 0.3-mm double amplitude (in X, Y, and Z directions for 10 minutes each)
Destruction: 10 to 25 Hz, 2-mm double amplitude (in X, Y, and Z directions for 2 hours each)
Malfunction: 98 m/s² (approx. 10 G) in X, Y, and Z directions
Destruction: 294 m/s² (approx. 30 G) in X, Y, and Z directions
Set time value
Approx. ±30% of the maximum setting value
Electrical: 10,000 operations
Operating: −10 to 60 °C (with no icing)
Storage: −25 to 65 °C
35% to 85%
2,000 m max.
Note: This means that no malfunction occurs with the open-phase element, but the operating value of the overload element may vary.
