PRODUCT DESCRIPTION
SIEMENS 3RT1956-6D - Surge Suppressor
This component is a varistor-type surge suppressor engineered for direct integration with SIEMENS SIRIUS 3RT1 series power contactors, specifically designed for frame sizes S6 through S12. It provides essential transient overvoltage protection for the contactor's coil, effectively mitigating inductive voltage spikes generated during coil de-energization. This accessory enhances the operational reliability and extends the service life of control circuit components in demanding industrial motor control and switching applications.
