OLR is the relay which senses the overload current i.e more than 100% of the motor capcity, whereas MPCB breaks the circuit during shortcircuit i.e current in the range of 5 to 10 times the rated current.

Which are resistive loads & which one are inductive loads : Refrigerator, Split air conditioner, ceiling fans, well pump, fluoresecent bulbs, T.V, CRT Monitors, Adsl Routers, C.P.U, Printers, Deep Freezers, Speakers, DVD Players, Microwave oven etc. ? Output Power for these Appliances Would be same like this : P = V * A * P.F Or would be changed ? thanks
