A motor protection circuit breaker is a protective device used to protect electric motors from overload, short-circuit, and other abnormal operating conditions that can damage the motor or pose a safety risk.

 

The main function of a motor protection circuit breaker is to interrupt the electrical circuit supplying the motor in case of overcurrent, preventing damage to the motor and the electrical system to which it is connected. This is especially important in industrial applications, where electric motors are often used in critical equipment and operate under variable load conditions.

 

MO325-4 Magnetic Only Motor Starter 4 A

 

The MO325-4 magnetic-only motor starter is a 54 mm wide device with a rated operational current of Ie = 4.0 A. This device is used for manually switching motors ON and OFF and reliably protecting them from short-circuits without the need for a fuse. The magnetic-only manual motor starter offers a service short-circuit breaking capacity Ics = 100 kA at 400 V AC. Other features are the integrated disconnect function, trip-free mechanism and a rotary handle with a clear switch position indication. The magnetic-only manual motor starter is suitable for three- and single-phase applications only. Auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power feeding blocks are available as accessories.
