Due to the wide current setting ranges and various tripping characteristics, complete series of motors are covered with just a few types. With their low heat loss, they are particularly energy-efficient and help to minimize temperature rises. Can be supplied with different setting ranges of the overload release and with different trip classes. They are available with screw or spring-loaded terminals for fast, maintenance-free and vibration-proof connection, as well as for stand-alone installation.
