3RU2136-4JB1
The Siemens SIRIUS 3RU2136-4JB1 is an S2-size thermal overload relay with a current range of 54 to 65 A. Its stand-alone design allows for independent configuration on a control panel and is suitable for distributed wiring configurations.
Product Positioning
The Siemens SIRIUS 3RU2136-4JB1 is an S2-size thermal overload relay with a current adjustment range of 54 to 65A. It features a stand-alone mounting design and is suitable for control panel configurations that are not directly connected to the contactor.
Core Product Advantages and Features
54-65A current range
The current scale is suitable for rated current protection of medium and large three-phase motors.
Individual installation of elastic
No contactor needs to be directly mounted; the installation position can be flexibly configured according to the space available on the control panel.
Screw terminal design
Both the main circuit and the auxiliary circuit use screw terminals, and the wiring construction method is the same.
Class 10 Breakthrough Level
It conforms to the IEC standard heat accumulation action curve, providing stable and reliable overload protection.
