3RU1116-0GB0
The 3RU1116-0GB0 is a Siemens SIRIUS 3RU11 series S00 thermal overload relay with an adjustment range of 0.45~0.63A. It features Class 10 tripping characteristics and phase loss protection, supports manual/automatic reset, and can be directly connected to a 3RT101 contactor to provide reliable overload protection for small-power motors.
Product Positioning
The 3RU1116-0GB0 is a Siemens SIRIUS series S00 size thermal overload relay with a current setting range of 0.45~0.63A. It is designed for direct connection to 3RT101 series contactors and provides dual protection against motor overload and phase loss.
Core Product Advantages and Features
Class 10 (Standardization Level)
Adopting the IEC standard Class 10 tripping characteristics, it provides a timely action after an appropriate delay when the motor is abnormally overloaded, balancing stable start-up and immediate protection.
Phase loss protection design
It has a built-in three-phase phase loss detection function, which can immediately cut off the power when any phase current is abnormally missing, so as to prevent the motor from burning out the windings due to single-phase operation.
Manual/Automatic Reset Switching
The system allows users to choose between manual or automatic reset modes depending on site requirements, making it convenient for maintenance personnel to quickly restore production line operation after troubleshooting.
S00 size direct mounting design
Both the electrical and mechanical structures are optimized for 3RT1015/3RT1016/3RT1017 contactors. They can be directly mounted on the contactors to save control box space, or they can be installed independently with DIN rails or base plates.
