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

That is right. Standard JIS C 4602 defines it shall be 50ms or shorter when 200% of the settling value is input.

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

It means multiples of the settling value. For example, when an instantaneous factor operation settling value of a relay

Because this relay derives the control power from input of the CT secondary current, when the input current falls below

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

Overload tolerance of an over current relay is 200 A, 1 second. Adjust CT ratio and others not to input more than 200 A.

The prohibition position sets the maximum settling value. With the definite time current, all prohibition positions set
