It is required that the resistance is lower than 5 ohm for a go and return length using sealed cables. Other than MPD-3

This relay uses the input voltage at the VT secondary side (P1-P2) as the relay control power source. When a rated volta

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

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.
