The Siemens 3RT2916-1CB00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for use with compatible 3RT2.1 contactors and 3RH2 auxiliary contactors. This contactor coil surge suppressor is designed to reduce switching transients generated when inductive contactor coils are energized or de-energized, helping reduce electrical interference in control circuits and supporting reliable operation of industrial automation systems.
The 3RT2916-1CB00 RC element surge suppressor supports 24–48V AC at 50/60Hz and 24–70V DC, making it suitable for a variety of AC and DC contactor control applications. Siemens specifies this accessory for S00-size contactors and identifies it as part of the SIRIUS surge suppressor family.
Using RC element suppression technology, the Siemens 3RT2916-1CB00 helps limit voltage transients and switching interference associated with contactor coils. It is particularly suitable for industrial motor control panels, DOL motor starters, PLC control panels, machine automation systems, OEM control cabinets, MCC applications and electrical switching equipment.
The accessory is designed for convenient clip-on mounting on compatible Siemens devices and can be installed in any mounting position. Its compact dimensions of 46 mm × 28 mm × 9 mm make it suitable for space-efficient electrical control-panel installations. The specified operating ambient temperature is -25°C to +60°C, while the storage temperature range is -40°C to +80°C.
The Siemens 3RT2916-1CB00 is an ideal choice for panel builders, OEMs, automation engineers and maintenance teams looking for a reliable Siemens contactor surge suppressor for compatible 3RT2.1 and 3RH2 devices.

Genuine Siemens SIRIUS accessory
The Siemens 3RT2916-1CB00 is a SIRIUS RC element surge suppressor designed for compatible 3RT2.1 contactors and 3RH2 auxiliary contactors. It helps suppress switching transients associated with contactor coils.
The 3RT2916-1CB00 supports 24–48V AC at 50Hz and 60Hz.
The specified DC control supply voltage is 24–70V DC.
This accessory is designed for Siemens 3RT2.1 contactors and 3RH2 auxiliary contactors, with S00 contactor size specified by Siemens.
The 3RT2916-1CB00 uses an RC element for suppression of switching transients and electrical interference.
Yes. Siemens specifies the device for 24–48V AC and 24–70V DC control supplies.
No. This model is an RC element surge suppressor, rather than a varistor-with-LED version.
The accessory uses clip-on mounting and can be installed in any mounting position on compatible Siemens devices.
The specified dimensions are 46 mm × 28 mm × 9 mm.
The operating ambient temperature range is -25°C to +60°C, while the storage temperature range is -40°C to +80°C.
No. The 3RT2916-1CB00 is a contactor surge suppressor accessory, not a complete contactor. It is designed for use with compatible Siemens 3RT2.1 and 3RH2 devices.
The Siemens 3RT2916-1CB00 provides RC-based suppression for compatible contactor coils across 24–48V AC and 24–70V DC. Its compact construction and clip-on installation make it suitable for industrial automation, motor control, OEM panels and machine-control applications.
