Siemens contactor 3RT1 series model parameters and application circuit diagram

Overview of Siemens Contactor 3RT1 Series

The standard implemented by this series of Siemens contactors is IEC/EN 60947-4-1, and according to IEC 60529, its reliability and safety are high (exception: series resistance S2 and S3), and the size is S0 to S3 The auxiliary conductor and coil terminals are all spring-type terminals.

Siemens contactor control and auxiliary circuits can be used for conventional coils (only sizes S00 and S0), coils with series resistance and coils with solid-state control units. The allowable ambient temperature for contactor operation (-40°C to +70°C in the entire coil working range. Uninterrupted operation at temperatures> +60°C will reduce mechanical durability, current carrying capacity of the conductive path and switching frequency.

Siemens contactor 3RT1 series application range

It is suitable for operation in equipment that undergoes considerable changes in control voltage and high ambient temperature, such as railway applications and rolling mills under extreme climatic conditions. The 3RT10 model Siemens contactor has traditional coils in the sizes S00 and S0. The working range of these contactor relays is 0.7 to 1.25xUs. The coil is equipped with a varistor as a standard configuration and does not require additional series resistance. It should be noted that the contactor of size S00 cannot be installed with auxiliary switch block, and the contactor of size S0 can be installed with two single-pole auxiliary switch blocks at most.

Siemens contactors are installed and used in the ambient temperature range> 60℃≤70℃. Side-by-side installation requires a gap of 10mm. The 3RT10 model contactor sizes S0 to S3 have series resistance, and the DC solenoid system of the contactor is modified by series resistors (to maintain excitation).

Siemens contactor 3RT1 series auxiliary switch

The size S00 contactor is pre-connected with a plug-in module containing a series resistor, and the varistor is integrated. The integrated NC contact is used to switch series resistance, and a 4-pole auxiliary switch group (in accordance with EN 50005) can also be installed.

The front side of Siemens contactors of sizes S0 to S3 is equipped with an auxiliary switch module with 2 NO+2 NC contacts, and a separate series resistor is horizontally connected next to the contactor on the 35mm standard mounting rail, equipped with a connecting cable It is installed on the contactor. The circuit diagram showing the terminals is pasted on each contactor. The series resistor function requires the normally closed contacts 21-22 of the auxiliary contacts. The selection and ordering data shows the number of additional unallocated auxiliary contacts.

Functional characteristics of Siemens contactor 3RT1 series

3RT10 type contactor, size S00 to S3 specification, with electronic contactor control unit, can expand the working range. They are provided as a complete unit with a built-in contactor control unit. The equipment is powered by the upstream control electronics to ensure that the coil working range is 0.7 to 1.25xUs and the ambient temperature is 70°C. The varistor is integrated to suppress the open circuit surge in the coil. Therefore, the opening delay is 2 to 5ms longer than the standard contactor, and the possibility of installing an auxiliary switch is the same as the installation of an equivalent standard Siemens contactor.
