Why Overload relay required with motor as the MCB/MCCB is capable to provide overload protection?

Why is the Overload relay required in the motor circuit, though the Breaker already has a provision for overload protection?

how about the inrush current? OLR will trip the circuit?

[@electricalconcept32]

OLR will not trip for inrush current

L S I G are some setting in ACB and mCCB FROM WHERE WE CAN SET INRUSH CURRENT AND ITS TIME DELAY

Watch my video micrological control setting of ACB

​ @electricalconcept32 can you please make a series of videos on light current system course?
