SIEMENS surge suppressor for S00 contactors
The SIEMENS 3RT29161CB00 is an RC coupling surge suppressor designed to protect Series 3RT2 S00 frame contactors. It clamps transients on both 24-48 V AC and 24-70 V DC control circuits. The accessory mounts directly onto the compatible contactor frame.
Ideal for panels using S00 frame contactors
This suppressor suits engineers fitting Series 3RT2 S00 contactors who need to limit switching spikes on low-voltage coils. It will not fit larger frame sizes or contactors outside the stated series, so buyers with different frames should look elsewhere.
Mounts on the contactor to free DIN-rail space
Because the suppressor attaches directly to the S00 contactor, it does not occupy additional DIN-rail slots or require separate wiring ducts. The RC network handles both AC and DC control voltages, simplifying bill-of-materials for mixed-voltage panels.

Questions about this item
Which contactor frame size must I already have for the 3RT29161CB00 to mount correctly?
The suppressor is built for frame size S00 contactors in the 3RT2 series, so you need an S00 frame contactor for direct mounting.
Will the RC coupling in this suppressor interfere with the coil operation of my existing 3RT2 S00 contactor?
No, the RC coupling is designed to work with the 24-48 V AC or 24-70 V DC coil range of the 3RT2 S00 contactors without affecting normal operation.
How can I verify the suppressor is clamping transients at the rated 24-48 V AC or 24-70 V DC after installation?
Measure the voltage across the suppressor terminals during a switching event; the RC network should limit spikes to within the stated AC and DC voltage bands.
