Product Description

Siemens SIRIUS 3RU2116-0BB0 Thermal Overload Relay – Advanced Motor Protection for Industrial Applications

The Siemens SIRIUS 3RU2116-0BB0 Thermal Overload Relay is a dependable and high-performance motor protection device engineered to safeguard industrial motors against overload conditions, phase failure, and excessive current flow. As part of the globally recognized SIRIUS 3RU2 Series, the 3RU2116-0BB0 delivers precise thermal protection, helping industries maintain operational reliability, minimize downtime, and extend motor life.

Modern industrial systems rely heavily on motors for critical operations. Any unexpected overload can result in overheating, equipment damage, production losses, and costly maintenance. The Siemens 3RU2116-0BB0 Motor Protection Relay is specifically designed to detect abnormal current conditions and disconnect the motor before serious damage occurs. This proactive protection mechanism significantly enhances the safety and efficiency of electrical installations.

Manufactured under Siemens' renowned SIRIUS motor control portfolio, the 3RU2116-0BB0 Thermal Overload Relay utilizes advanced bimetal technology to provide accurate overload detection. The relay responds to thermal changes caused by excessive motor current and initiates tripping according to its Class 10 tripping characteristic, making it ideal for motors with normal starting conditions.

One of the key advantages of the Siemens 3RU2116-0BB0 is its compact S00 frame design, allowing seamless integration with compatible Siemens contactors and motor starter assemblies. The relay is engineered for direct contactor mounting, reducing installation complexity while ensuring secure and reliable operation in industrial environments.

The SIRIUS 3RU2 Series is widely trusted across industries such as manufacturing, automation, water treatment, HVAC systems, conveyors, pumps, compressors, and process control applications. Whether used in machine-building projects or large-scale industrial control panels, the 3RU2116-0BB0 overload relay provides consistent performance under demanding operating conditions.

A major benefit of this thermal overload relay is its protection against phase failure. In three-phase motor systems, loss of a phase can lead to severe overheating and motor burnout. The Siemens 3RU2116-0BB0 quickly identifies such conditions and activates protective tripping, reducing the risk of equipment failure and costly repairs.

The relay also features both manual and automatic reset functionality, giving maintenance personnel greater flexibility during troubleshooting and system restoration. This adaptability makes it suitable for a wide variety of industrial control strategies and motor protection requirements.
