The Siemens 3RT2916-1CD00 is a genuine SIRIUS RC element surge suppressor designed to protect contactor coils and control circuits from switching-induced voltage spikes and transient overvoltages. This front-mounted accessory is specifically developed for Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors (Size S00), ensuring reliable protection and improved operational stability in industrial automation systems.
Designed for 127–240V AC (50/60 Hz) and 150–250V DC control voltages, the 3RT2916-1CD00 effectively absorbs voltage surges generated during contactor switching operations. This helps safeguard PLC outputs, relays, timers, sensors, and other sensitive electronic control devices from transient electrical stress and premature failure.
The suppressor utilizes a proven RC element (RC coupling) design, which minimizes switching transients and reduces electromagnetic interference (EMI) within control systems. By reducing electrical noise, it helps prevent nuisance tripping, improves switching reliability, and enhances overall system performance.
Featuring a compact front-mount clip-on design, the 3RT2916-1CD00 can be installed quickly without additional wiring modifications. Suitable for mounting in any position, it offers a space-saving solution for motor control centers (MCCs), industrial control panels, HVAC systems, OEM machinery, and process automation applications.
The device operates reliably in ambient temperatures ranging from -25°C to +60°C and can be stored in temperatures from -40°C to +80°C. Manufactured according to Siemens quality standards, it carries CE, UL, and CSA certifications, ensuring compliance with international industrial requirements.
As part of the trusted Siemens SIRIUS 3RT29 accessories range, the 3RT2916-1CD00 RC Element Surge Suppressor delivers dependable coil protection, reduced maintenance requirements, and long-term reliability for industrial motor control and automation systems.
