Contact recovery delay after applying voltage

This relay has a capacitor to operate in case of the lost power or at the maximum settling of an operation time. Because this capacitor needs a time to be ch... 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 >>

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 >>

Combination transformer

It is required that the resistance is lower than 5 ohm for a go and return length using sealed cables. The high voltage receiving facility rule defines “The ... 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 >>

Combination transformer

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 >>

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 >>

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 operating time of the instantaneous factor operating characteristics

That is right. Standard JIS C 4602 defines it shall be 50ms or shorter when 200% of the settling value is input. More Details >>
