The Siemens 3RT2916-1BD00 is a genuine SIRIUS varistor 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 control system reliability and extend the service life of connected equipment.
Designed for 127–240V AC (50/60 Hz) and 150–250V DC control voltages, the 3RT2916-1BD00 effectively absorbs voltage 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 electrical stress and transient damage.
The suppressor utilizes proven varistor technology, providing fast and reliable transient voltage suppression while minimizing electromagnetic interference (EMI) within industrial control systems. By reducing electrical noise and voltage peaks, it improves switching reliability, prevents nuisance tripping, and enhances overall control circuit performance.
Featuring a compact front-mount clip-on design, the 3RT2916-1BD00 can be installed quickly without additional wiring modifications. Its compact dimensions and lightweight construction make it ideal for motor control centers (MCCs), industrial control panels, HVAC systems, OEM machinery, and automation applications where panel space is limited.
The device supports installation in any mounting position and operates reliably in ambient 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 approvals, ensuring compliance with international industrial requirements.
As part of the trusted Siemens SIRIUS 3RT29 accessories range, the 3RT2916-1BD00 Varistor Surge Suppressor delivers dependable coil protection, reduced maintenance requirements, and long-term operational reliability for industrial motor control and automation systems.
