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 >>
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 >>
Because when an undervoltage is detected, b contact will be closed, if power supply (P1-P2) is lost, the contact is retained. More Details >>
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 >>
It is required that the resistance is lower than 5 ohm for a go and return length using sealed cables. Other than MPD-3 type ZVT, it is similar to the distan... More Details >>
