Description
The Siemens 3RU1116-0GB0 is a compact thermal overload relay from the SIRIUS 3RU1 series, engineered to protect small three-phase motors from overload, phase asymmetry, and phase failure. With an adjustable current range of 0.45 to 0.63 A, it’s ideal for precision motor protection in low-power applications. This Class 10 relay features manual and automatic reset options and mounts directly onto compatible contactors such as the 3RT1015, 3RT1016, and 3RT1017. It uses screw terminals for both main and auxiliary circuits, ensuring secure and straightforward wiring.
