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 engineered for Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors (Size S00), helping improve system reliability and extend the service life of connected control equipment.
Designed for 127–240V AC (50/60 Hz) and 150–250V DC control voltages, the 3RT2916-1CD00 absorbs switching surges generated when contactor coils are energized or de-energized. This protection helps safeguard PLC outputs, relays, timers, sensors, and other sensitive automation devices from transient electrical stress and potential damage.
The suppressor utilizes a proven RC element (RC coupling) design, which effectively minimizes voltage peaks and reduces electromagnetic interference (EMI) in industrial control systems. By lowering electrical noise levels, it improves switching reliability, reduces nuisance tripping, and enhances overall control circuit stability.
Featuring a compact front-mount clip-on design, the 3RT2916-1CD00 can be installed quickly without additional wiring modifications. Its compact construction makes it ideal for motor control centers (MCCs), industrial control panels, OEM machinery, HVAC systems, and automation applications where space optimization is important.
The device is designed for reliable operation in demanding industrial environments, with an operating temperature range of -25°C to +60°C and storage temperatures from -40°C to +80°C. Manufactured according to Siemens quality standards, it carries CE, UL, and CSA approvals, ensuring compliance with international industrial standards.
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 improved operational reliability for industrial motor control and automation systems.
