PRODUCT DESCRIPTION
SIEMENS 3RT1955-5NF31 - Surge Suppressor RC Element
This component is a SIEMENS SIRIUS 3RT19 series surge suppressor, specifically an RC element designed for damping opening surges in industrial contactor applications. It integrates directly into SIEMENS SIRIUS 3RT1 contactors of sizes S6 through S12, mitigating transient overvoltages generated during inductive load switching. This device contributes to the operational stability of contactor coils and associated control circuitry in industrial automation systems.
