Product Positioning

The Siemens SIRIUS 3RU2136-4AB0 is an S2 frame thermal overload relay with a current adjustment range of 11 to 16 amps. It is designed for direct mounting on corresponding frame contactors and is used for overload and phase loss protection of three-phase motors.

Core Product Advantages and Features

S2 frame direct mounting

The contactor is designed for direct front mounting, eliminating the need for additional wiring to form a motor starting unit and saving control panel space.

11-16A Adjustable Setting

The panel knob allows for fine-tuning of the trip current within the range of 11 to 16 amps, closely matching the actual rated current of the motor.

Class 10 Breakthrough Level

It conforms to the IEC standard Class 10 operating characteristics and can avoid accidental tripping under normal motor starting load.

Manual/Automatic Reset

After the system detaches, users can choose to manually confirm or automatically revert, allowing for flexible use depending on production line safety requirements.
