3RU1126-1CD0

The Siemens SIRIUS 3RU1126-1CD0 thermal overload relay features an S0 frame, Class 10 operating rating, and a current setting range of 1.8~2.5 amps. The main circuit uses screw terminals, while the auxiliary circuit uses spring terminals, which differs from the B0 terminal models in the same series.

Product Positioning

The 3RU1126-1CD0 is a Siemens SIRIUS 3RU11 series S0 type frame thermal overload relay with a current setting range of 1.8~2.5 amps. The "D0" at the end of the model number indicates that the auxiliary circuit uses spring terminals, which is different from the screw terminal auxiliary circuit of the "B0" model in the same series.

Core Product Advantages and Features

Spring-type auxiliary terminal

The auxiliary circuit uses a spring-loaded terminal design, allowing for quick wiring and screwless fastening, unlike the screw-terminal version of the "B0" model.

Main circuit screw terminals

The main circuit retains the screw terminal type, balancing wiring stability and connection flexibility.

S0 type frame contactor assembly

It can be directly attached to contactors 3RT1023, 3RT1024, 3RT1025, and 3RT1026.

Class 10 protection level

Compliant with IEC standard tripping characteristics, suitable for overload protection of low-current small motors.
