What is the relay return factor?
so the relay returns the relay Coefficient has a special requirement, neither too high nor too low.
which relies on the sensitivity of the relay. The closer the value is, the more sensitive the relay is, but the relay with too high sensitivity is not suitable for a long time,
Is the ratio of the return value of the relay to the value of the action. Such as over-current relay return factor is
Return coefficient = return current / operating current,
