The Siemens 3RT2916-1JL00 is a genuine SIRIUS surge suppressor module featuring a varistor with integrated LED indicator, designed to protect contactor coils and control circuits from switching-induced voltage spikes. This front-mounted accessory is engineered for Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors (Size S00), helping improve system reliability and extend the lifespan of connected control components.
Designed for 127–240V AC (50/60 Hz) and 70–150V DC control voltages, the 3RT2916-1JL00 effectively suppresses transient overvoltages generated during contactor switching operations. By limiting voltage peaks, it protects PLC outputs, relays, timers, sensors, and other sensitive electronic equipment from electrical stress and potential damage.
A key feature of this suppressor is its integrated LED status indication, which provides clear visual confirmation of coil energization and control circuit operation. This simplifies troubleshooting, commissioning, and maintenance activities while improving visibility inside industrial control panels.
The module features a compact clip-on mounting design that allows quick installation without additional wiring modifications. Suitable for mounting in any position, it measures approximately 46 mm × 28 mm × 9 mm, making it ideal for motor control centers (MCCs), automation systems, OEM machinery, HVAC installations, and industrial control panels where space optimization is important.
By reducing switching transients and electromagnetic interference (EMI), the 3RT2916-1JL00 helps prevent nuisance tripping, reduces wear on switching devices, improves control circuit stability, and enhances overall system performance. Manufactured according to Siemens quality standards, it offers dependable long-term operation in demanding industrial environments.
As part of the trusted Siemens SIRIUS 3RT29 accessories range, the 3RT2916-1JL00 Varistor with LED Surge Suppressor provides reliable coil protection and seamless compatibility with Siemens motor control and automation products.
