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 >>

Combination transformer

That is described as below. (1) By laying ZCTs for two feeders having different loads, detected by one earth fault directional relay. In this case, it i... More Details >>

Position of switch

Because between memories, a value becomes unstable, reset the position to the correct position. More Details >>

Movement indicator

It operates. 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 >>

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 >>

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 >>

Combination transformer

It is impossible. It is required to combine with MZT type ZCT dedicated for our products. 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 >>

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 >>
