Can we use MCB instead of MPCB?

MCB : it is protected against only due to short circuit fault. not for any other Overload fault. MCCB : it is applicable for short-circuit , O/L protection, Also it has E/F protection feature. MPCB : Is is specially made for motor protection application, i.e. Overload & Shortcuit protection.

What is the difference between MCCB and Mpcb?

MPCB is specially designed for motor protection while in MCCB are specially designed for general-purpose circuit protection. MPCB can protect the motor against overload, short circuit, phase loss, and under-voltage faults while in MCCB can protect the motor against overload and short circuits.

Is Mccb better than MCB?

If evaluated from their power capacities, the MCB is essentially used for low-current requirements, such as, home wiring or small electronic circuits; while the MCCB is better used for high-power requirements….

Can we use MCB for motor protection?

In conclusion, an MCB is not adequate to protect your motor and using just an MCB is fraught with risk. Apart from this, an MPCB is easier to select as the motor ratings are clearly declared on the product itself. It is possible to tune it to your particular application with an accurately adjustable reference current.

How does Mpcb select motor?

Motor Protection Circuit Breaker Sizing (Selection Guide) The two main factors that determine the adequate motor protection circuit breaker size are the nameplate voltage and nameplate current, of the motor itself. The MPCB voltage rating must match the nameplate voltage of the motor.

What is the use of MPCB?

It has several functions that allow it to provide a safe electrical supply for motors: Protection against electrical faults such as short circuits, line-to-ground faults and line-to-line faults. The MPCB can interrupt any electrical fault that is below its breaking capacity.
