3RU2136-4JD0
The Siemens SIRIUS 3RU2136-4JD0 is an S2-size thermal overload relay with a current range of 54 to 65 A. The difference between it and the 4JB0 model with the same current value is that the auxiliary circuit uses a spring-loaded terminal design, allowing for tool-free, quick crimping of the wiring.
Product Positioning
The Siemens SIRIUS 3RU2136-4JD0 is an S2-size thermal overload relay with a current adjustment range of 54 to 65A. Like the 4JB0 with the same current, it is a direct-connect type, but the difference lies in the auxiliary circuit which uses a spring terminal design.
Core Product Advantages and Features
Spring terminal auxiliary circuit
The auxiliary circuit uses a spring terminal design, allowing for quick wiring without the need for screw fastening.
Main circuit screw terminals
The main circuit still uses screw terminals to ensure the contact reliability of high-current wiring.
54-65A current range
The current scale is suitable for rated current protection of medium and large three-phase motors.
Direct mounting
It can be directly mounted on SIRIUS 3RT203 series contactors, simplifying installation.
