The Siemens 3RT2916-1CB00 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 designed for Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors (Size S00), ensuring enhanced reliability and protection for industrial automation systems.
Designed for 24–48V AC (50/60 Hz) and 24–70V DC control voltages, the 3RT2916-1CB00 effectively suppresses transient surges generated when contactor coils are energized or de-energized. This protection helps safeguard PLC outputs, relays, timers, sensors, and other sensitive control devices from electrical stress and potential damage.
The suppressor utilizes a proven RC element (RC coupling) design, which minimizes voltage peaks and reduces electromagnetic interference (EMI) within industrial control systems. By reducing electrical noise, it improves switching reliability, prevents nuisance tripping, and enhances overall control circuit performance.
Featuring a compact front-mount clip-on design, the 3RT2916-1CB00 can be installed quickly without additional wiring modifications. Its compact dimensions of 46 mm × 28 mm × 9 mm make it suitable for motor control centers (MCCs), industrial control panels, OEM machinery, HVAC systems, and process automation applications where panel space is limited.
The device supports installation in any mounting position and operates reliably in temperatures ranging from -25°C to +60°C, with storage 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 3RT2916-1CB00 RC Element Surge Suppressor provides dependable coil protection, reduced maintenance requirements, and long-term operational reliability for industrial motor control and automation systems.
