The Siemens 3RT2926-1CD00 is a genuine SIRIUS RC element surge suppressor designed to protect contactor coils and associated control circuits from harmful switching surges and transient overvoltages. Specifically engineered for Siemens SIRIUS 3RT2.2 contactors (Size S0), this accessory helps improve system reliability, reduce electrical noise, and extend the service life of control components.
The suppressor is suitable for 127–240V AC (50/60 Hz) and 150–250V DC control voltages. When connected across the contactor coil, the RC element absorbs voltage spikes generated during switching operations, protecting sensitive devices such as PLCs, relays, timers, sensors, and electronic controllers from transient damage.
Designed as a compact clip-on accessory, the 3RT2926-1CD00 can be installed quickly and easily without requiring additional wiring modifications. Its compact dimensions and lightweight design make it ideal for motor control centers (MCCs), industrial control panels, automation systems, OEM machinery, and process control applications.
By suppressing coil-generated transients and reducing electromagnetic interference (EMI), the RC element helps prevent nuisance tripping, improves switching reliability, minimizes contact wear, and enhances overall control system stability. These advantages contribute to lower maintenance costs and increased operational efficiency in industrial environments.
The 3RT2926-1CD00 is manufactured according to Siemens quality standards and carries major international approvals including CE, UL, and CSA. It is part of the trusted Siemens SIRIUS 3RT29 accessories range, ensuring seamless compatibility with Siemens motor control and automation products.
