3RU2116-1CB1
The 3RU2116-1CB1 is a stand-alone overload relay with a current setting range of 1.8~2.5A. It features screw terminal connection and can be wired independently without being mounted on a contactor. It has a CLASS 10 tripping characteristic and is suitable for S00 class motor circuits.
Product Positioning
The Siemens SIRIUS 3RU2116-1CB1 is an S00 size thermal overload relay with an independent mounting base and screw terminals. It has an operating current of 1.8~2.5A and is suitable for control panel configurations that are not co-installed with contactors.
Core Product Advantages and Features
Independent installation design
It uses an independent terminal block for fixing, so it does not need to be mounted on the contactor, making wiring location and maintenance more flexible.
Screw terminal connection
Both the main circuit and the auxiliary circuit use traditional screw terminals, and the wiring method is compatible with the existing panel.
Precise current adjustment
The current setting range is 1.8~2.5A, and the trip point can be finely adjusted according to the actual load of the motor to reduce the risk of false tripping.
CLASS 10 Skip Level
It conforms to the IEC 60947-4-1 standard CLASS 10 operating characteristics, providing stable overload protection response time.
