3RT1956-1CB00
The Siemens SIRIUS S6/S10/S12 frame large contactor RC surge suppressor is suitable for low-voltage coil voltages of 24~48VAC/24~70VDC and is commonly used in automated production lines that use 24VDC control power supplies.
Product Positioning
The 3RT1956-1CB00 is an RC surge suppressor suitable for Siemens SIRIUS large contactors (S6, S10, S12 frames). It is compatible with 24~48VAC or 24~70VDC low-voltage coils and is particularly suitable for automated production lines that use 24VDC as the control power supply. It can effectively reduce induced surge interference when the coil is de-energized.
Core Product Advantages and Features
Low voltage coil applicable
This corresponds to common 24V control power supply voltage ranges such as 24~48VAC/24~70VDC.
RC absorbs surge
The resistor-capacitor combination absorbs the instantaneous induced surge voltage released by the coil.
Suitable for large frames
SIRIUS large contactor operating mechanisms covering S6, S10, and S12 frames
Easy to install
The screw terminal connection method facilitates on-site replacement and maintenance.
Reduce system noise
Reduce surge interference to the 24VDC control circuit and PLC output points
