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 >>

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 >>

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 >>

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 >>

Detection of current

It operates on a root mean square value of a fundamental wave. More Details >>

Position of switch

The prohibition position sets the maximum settling value. With the definite time current, all prohibition positions set 6 A, and with the instantaneous curre... More Details >>
