WHEN I AM CONNECTIN TWO ELCB IN PARALLEL.ONE ELCB
TRIPPED...HOW IT HAPPEND??

Answer Posted / purushotham

the ELCB's are connected in parllel, so the voltage in the
ckt is equal but current is diff. so if one coil trips the
ckt will works on second ELCB and total loading depends on
that second ELCB.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
