Siemens 3RT2916-1BB00 SIRIUS Surge Suppressor, Varistor for 3RT2.1 & 3RH2 Contactors Original Brand New

Overview

The Siemens 3RT2916-1BB00 is an essential plug-in accessory for the SIRIUS modular system. As a varistor-based surge suppressor, it clips directly onto the front of size S00 contactors. It is specifically engineered to damp opening surges (voltage spikes) at the coil, protecting sensitive electronic controllers (like PLCs) from electromagnetic interference and potential damage.

Key Benefit

• Enhanced Equipment Lifespan: Prevents high-voltage peaks from damaging coil insulation and nearby electronic components.

• Easy Installation: Tool-free, plug-in design allows for rapid mounting onto the front of the contactor.

• Universal Compatibility: Works seamlessly with both AC and DC control voltages within the specified range.

• Compact Footprint: Fits within the standard dimensions of the S00 frame size without requiring extra rail space.

Function

• Suppresses transient voltage spikes during switching operations

• Stabilizes electrical circuits in AC and DC applications

• Minimizes electromagnetic interference (EMI)

• Ensures smooth and safe contactor operation
