Movement indicator

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

Short-circuit detection

Overload tolerance of an over current relay is 200 A, 1 second. Adjust CT ratio and others not to input more than 200 A. More Details >>

The viewpoint of the instantaneous fa...

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 >>

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 >>

About contact

Because when an undervoltage is detected, b contact will be closed, if power supply (P1-P2) is lost, the contact is retained. More Details >>

Movement of contact

This relay uses the input voltage at the VT secondary side (P1-P2) as the relay control power source. When a rated voltage is input, b contact side of the co... More Details >>
