RC Snubber for SIRIUS Contactors
The 3RT2926-1CE00 is an RC-element surge suppressor designed to clip directly onto SIRIUS S0-size contactors (3RT2.2 series). It suppresses voltage spikes from the AC coil during de-energization, protecting nearby electronics and extending contact life. Rated for 240–400 V AC at both 50 Hz and 60 Hz, it covers the common line voltages found in industrial panels worldwide.
Fit and Mounting
Dimensions are 12 mm deep, 30 mm wide, and 19 mm tall — it adds minimal width to the contactor assembly on the DIN rail. Clip-on fastening means no tools or extra hardware are required; it snaps onto the contactor in any mounting position.
Environmental and Compliance
Operating temperature range is -25 to +60 °C, with storage from -40 to +80 °C — suitable for standard panel environments without derating. RoHS compliance date is 10/01/2009, indicating it meets the EU substance restrictions for electronic equipment.
