Answer Posted / nabeel
MCCB - Thermomagnetic operaton-For large surges in ct- In
distribution boards-bimetallic strip responding to less
extreme but longer_term over_current conditions-applicable
for
low voltages.
ACB - low volt power cb-trip characteristics r
adjustable-air s the arc quenching medium-applicable upto 440V.
VCB - medium volt power cb-trip char. adjustable-mechanical
sys. used for trip & open-Vaccuum s the arc quenching
medium-applicable upto 36kV.
