MCB- MCB's are in rated capacity,these are not having any
range i.e if we take a 10A mcb,it will operate beyond that
only and these are open type(i.e not having any asing or en
closer.
MCCB-MCCB means moulded case circuit breakers,which is
having current range setting capability like relays. if mccb
is of range from 200A,we can set the operating range in b/w
min and max.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
