The Siemens 3RU2116-1CB1 is classified as a thermal overload relay, specifically designed to handle overload protection. This relay consists of 2 poles for the main current circuit and incorporates one normally open (NO) contact alongside one normally closed (NC) contact to accommodate different application requirements. The device features screw-type terminals for reliable electrical connections.

With a trip class rating of Class 10, the relay is calibrated for effective protection, activating when the operating current of up to 2.5 Amperes is exceeded. It has a temperature resilience ranging from -40 to 70°C in non-condensing environments, providing versatile deployment across various industrial setups. The device allows for an operational frequency within the range of 50 to 60 Hertz.

In terms of environmental endurance, the 3RU2116-1CB1 can resist surge voltages of 6 kilovolts and can be stored in temperatures from -55 to 80°C. Designed for use at installation altitudes of up to 2,000 meters (6,561.68 feet) above sea level, it maintains reliability at significant elevations. Additionally, the relay can be mounted in any orientation, offering flexibility depending on the specific setup requirements.
