The Siemens 3RT2916-1JK00 is a genuine SIRIUS surge suppressor featuring a varistor with integrated LED indication, designed to protect contactor coils and control circuits from switching-induced voltage spikes. This front-mounted accessory is specifically engineered for Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors (Size S00), ensuring enhanced protection and operational reliability in industrial control systems.
Designed for 48–127V AC (50/60 Hz) and 24–70V DC control voltages, the 3RT2916-1JK00 effectively suppresses transient overvoltages generated when contactor coils are energized or de-energized. This protection helps safeguard PLC outputs, relays, timers, sensors, and other sensitive automation components from electrical stress and premature failure.
A key feature of this suppressor is its integrated LED status indicator, which provides immediate visual confirmation of coil energization and control circuit status. This simplifies commissioning, troubleshooting, maintenance, and fault diagnosis while improving visibility within electrical control panels.
The module utilizes a compact front-mount clip-on design, allowing quick installation without additional wiring modifications. With dimensions of approximately 46.4 mm × 28 mm × 8.6 mm, it is ideal for motor control centers (MCCs), industrial automation systems, OEM machinery, HVAC applications, and process control panels where space optimization is essential.
By reducing switching transients and electromagnetic interference (EMI), the 3RT2916-1JK00 helps prevent nuisance tripping, reduces contact wear, improves control circuit stability, and extends the lifespan of connected equipment. Manufactured according to Siemens quality standards, it delivers dependable long-term performance in demanding industrial environments.
As part of the trusted Siemens SIRIUS surge suppressor range, the 3RT2916-1JK00 Varistor with LED provides reliable coil protection and seamless compatibility with Siemens motor control and automation products.
