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 >>

Movement indicator

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

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 >>

A lighting condition of RUN

Because this relay derives the control power from input of the CT secondary current, when the input current falls below about 0.5 A for 2-phase input or abou... 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 >>

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 >>

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 >>

Return of contact

The contact recovers automatically. More Details >>

Combination with other companies' peripheral devices

It is impossible. In Standard JIS C 4609, warranty is covered for combination of peripheral devices and relays. Therefore, combination with other companies’ ... More Details >>
