Description
The Siemens 3RU2116-1GB0 is a thermal overload relay engineered to protect motors from damage due to overload conditions in industrial control circuits. Designed to work seamlessly with S00-sized contactors, it offers an adjustable current range from 4.5 to 6.3 A, making it ideal for safeguarding motors up to 2.2 kW at 400 V. This device includes both manual and automatic reset options, enabling flexible recovery depending on application needs. It comes equipped with integrated auxiliary contacts—one normally open (1 NO) and one normally closed (1 NC)—for enhanced control and signaling.
