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 >>

Scope of Application

It is impossible. Because the type is to detect by ZCT in an ungrounded system, the sensitivity becomes very high. More Details >>

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 >>

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 >>

Detection of current

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

The application of the overcurrent relay

It is possible. Connect R-phase to the terminal for R-phase of the relay, and T-phase to the terminal for T-phase of the relay. And the direction of a curren... More Details >>
