Fuses are devices containing a small piece of special wire that melts when the intensity of the current flowing through it for a certain period of time exceeds a set value thus protecting the rest of the electrical circuit overloads.
Motor protection circuit breaker symbol.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected.
This symbol represents circuit breaker with three poles.
Motor circuit protectors motor circuit protectors provide short circuit protection for individual motor loads and are available for a wide range of motor sizes and installation types.
Fuses and electrical protection symbols.
They can be combined with our nema and iec motor starters overload relays and contactors.

Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume.
Such kind of breakers is used in three phase systems in industries.
The mpcb can interrupt any electrical fault that is.
A motor protection circuit breaker or mpcb is a specialized electromechanical device that can be used with motor circuits of both 60 hz and 50 hz it has several functions that allow it to provide a safe electrical supply for motors.
