SIRIUS 3RB30 electronic overload relays for standard applications are responsible for current-dependent overload protection of electrical loads (e.g. motors). Due to the wide current setting ranges and various tripping characteristics, this complete series of motors are covered with just a few different options. The 3RB31 version offers enhanced functions including, but not limited to: integrated, electrical remote reset or ground fault detection.
