what is motor protection circuit breaker？
Motor protection circuit breakers are specialized types of electrical protection devices that are designed specifically for electric motors as their name implies. Electric motors have plenty of applications and are used to drive mechanical devices of all types, so it is very important to protect them adequately with MPCBs.
The following are just a few examples of devices driven by electric motors in commercial and industrial buildings:
Rooftop air conditioners, chillers, compressors, heat pumps, and cooling towers.
Extraction and injection fans, as well as air handling units.
Water pumping systems.
Elevators and other hoisting devices.
Industrial conveyor belts and other machinery used in manufacturing processes.
