The Siemens SIRIUS 3RB series is a solid-state overload relay for inverse-time delayed protection of loads with normal and heavy starting against excessive temperature rises due to overload， phase unbalance or phase failure which has a current rating up to 1.2 A。It has manual or automatic reset switch functionality。It has a size S0。It can be mounted with contactor mounting。The type of electrical connection for main circuit and for auxiliary circuit is through screw-type terminal。Due to the wide current setting ranges and various tripping characteristics， complete series of motors are covered with just a few types。It has low heat loss which makes it energy-efficient and help to reduce the temperature rise in the control cabinet.Ambient operating temperature is -25 to +60℃ Operating frequency is 50 to 60 Hz Trip class is CLASS 10E。
