The reactive circuits (capacitor) require a high level of current to start the charging.
1694 is a smart device which can allow the Inrush Current requirements of the capacitive circuit.
Whereas the Z and B MCBs cannot differentiate between the Inrush requirements
of a highlight capacitive circuit or a high impedance short—therefore these MCBs result in a false tip.
The C MCB breaker however allows the inrush current based on the Current-Time Characteristics.
