PRODUCT DESCRIPTION
SIEMENS 3RT5965-5AR31 - Surge Suppressor (RC Element)
The SIEMENS 3RT5965-5AR31 is an RC element surge suppressor from the SIRIUS 3RT59 accessory series. It is engineered to provide transient voltage protection for the coil circuits of SIEMENS SIRIUS 3RT5 power contactors, specifically those in sizes S6 through S12. This component mitigates inductive voltage peaks generated during contactor switching, thereby enhancing the operational stability and extending the service life of control system components in industrial automation and motor control applications.
