5 ways that motor circuit breakers provide optimal protection for motors
It’s estimated that there are more than 300 million electric motors in the world being used in industry, infrastructure, and large buildings, with electric motor-driven systems (EMDS) accounting for between 43-46% of all global electricity consumption . Motors drive everything from processes, to commercial heating, ventilating, cooling, and refrigeration. With business productivity so dependent on them, it’s important that they’re properly protected. In most jurisdictions, motor protection is mandatory, so OEM machine builders and electrical contractors will ensure that there is a circuit breaker used on each motor circuit. If the proper type of motor circuit breaker is selected, the motor will be adequately protected. Unfortunately, there are many examples in which a standard electrical distribution circuit breaker was chosen for this purpose. These breakers are typically selected because they are lower cost. But they are designed to protect standard types of circuits and loads, no...
