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 >>

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 >>

Movement indicator

Set the frequency to meet the frequency of the region. Incorrect frequency prevents correct detection. 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. The high voltage receiving facility rule defines “The ... More Details >>

Burden of MOC-A1 type

In steady state, it is 5.0 VA, and during operation, it is 6.0 VA. More Details >>

Direction of the current in the incident detection

It is possible. More Details >>
