The viewpoint of the instantaneous factor operating characteristics graph

It means multiples of the settling value. For example, when an instantaneous factor operation settling value of a relay is 30 A, 100% is read as 30 A. More Details >>

Operating time of undervoltage detection

It operates with a settled operation time. More Details >>

Confirmation method of the start-up value

Set the display selection switch on the front upper right of the relay to “Time limit pass.” When a relay detects near the operation value, “0” will be displ... More Details >>

Burden of MOC-A1 type

In steady state, it is 5.0 VA, and during operation, it is 6.0 VA. More Details >>

Movement indicator

Set the frequency to meet the frequency of the region. Incorrect frequency prevents correct detection. More Details >>

Position of switch

Because between memories, a value becomes unstable, reset the position to the correct position. More Details >>

About contact

Because the contact capacity is different to that of a contact for trip, it cannot be used for tripping. Refer to the catalog for the contact capacity. More Details >>
