Rated current

In CT circuit, it is 5 A. More Details >>

Detection of current

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

Direction of the current in the incident detection

It is possible. 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 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 >>

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 >>

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 >>

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 >>
