The Siemens SIRIUS 3RB series is manual-automatic reset solid-state overload relay used for higher-level applications for the current and temperature-based protection of loads with normal and heavy starting against impermissibly high heat generation. The type of electrical connection for main circuit and auxiliary circuit is through screw terminal.
Due to wide current setting ranges and various tripping characteristics, entire series of motors are covered with just a few types. It has low heat loss which makes it energy-efficient and help to minimize temperature rises in the control cabinet.
Ambient operating temperature is -25 to +60 °C
Operating frequency is 50 to 60 Hz
Trip class is CLASS 5, 10, 20 and 30 adjustable
