3RB3113-4TB0
The Siemens SIRIUS 3RB3113-4TB0 electronic overload relay has a current setting range of 4~16A, S00 size, and trip levels that can be switched between 5E and 30E. It supports manual/automatic reset and remote reset functions and is suitable for overload and phase loss protection of three-phase motors.
Product Positioning
The SIRIUS 3RB3113-4TB0 is a Siemens S00-size electronic overload relay with a current setting range of 4~16A and adjustable trip levels from 5E to 30E. It is suitable for contactor mounting and can be used with 3RT contactors to form a motor protection unit.
Core Product Advantages and Features
Adjustable skip level
The overload protection response time can be flexibly set according to the motor starting characteristics by switching between 5E, 10E, 20E, and 30E.
Built-in ground fault detection
It has a ground fault detection function with a sensitivity of approximately 0.75 times the rated current of the motor, thus improving system safety.
Manual/Automatic and Remote Reset
It supports manual and automatic reset switching and provides a DC 24V remote reset terminal for convenient on-site and remote maintenance operations.
Contactor mounting design
It can be directly mounted on Siemens 3RT series contactors and used with 1NO+1NC auxiliary contacts to report operating status.
