1.what is the difference between MPCB and MCB ?
2.what is the difference between MPCB and MCCB ?
Answer Posted / rohan
MCB(Miniature Circuit Breaker) which ranges from 0.5A to
63A, but now HRC MCB has rating upto 125A, anything higher
than this rating requires a design which can handle so high
current so MCCB(Moulded Case Ciruit Breaker) which has raing
upto 1000A, whereas, MPCB is used for Motor Protection Device.

A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
