Power Protection: While the motor is powering a load, the optional sensing module with voltage, current, and ground fault current, will also protect the motor based on power.
For example, in a pumping application, electronic motor protection devices can simulate the internal temperature of an electrical motor providing mechanical power to a pump. They can send an alarm by text message or email if the heat rises beyond a specified level.
Motor Protection Circuit Breakers (MPCBs) combine the short-circuit and isolation functionality of a molded case circuit breaker with the motor overcurrent protection of a traditional overload relay. These devices are traditionally used in two-component starter applications, with a contactor to control a motor load.
In North America, electrical codes require that an individual motor branch circuit be protected by a UL/CSA listed fuse, circuit breaker, or self-protected combination motor controller. The elimination of individual motor circuit fuses or circuit breakers means significant panel size reduction.
Correct motor protection setup and configuration is essential to ensuring proper operation, performance, and efficiency of a motor. Key elements to ensuring correct protection setup of the motor relies on the Motor Performance Data, or Motor Nameplate Data, which is supplied by the motor manufacturer.
Older (electromechanical) motor protection technology will protect a motor from overheating by shutting the motor down – but that’s reactive (after the problem) rather than proactive. Production stops while the motor recovers – potentially risking hundreds of thousands of dollars in revenue.
