Active production — what that means for your BOM line
The 3RT2916-1BE00: As a SIRIUS-branded accessory, it shares the same compliance documentation as the contactor range it serves — RoHS compliance dated 10/01/2009 per the substance prohibition date, which covers the EU RoHS directive requirements.
Varistor suppression — what the 240-400 V AC rating covers
This is a varistor-type surge suppressor, meaning it clamps voltage transients across the contactor coil by shunting the spike through a metal-oxide varistor element. The varistor design handles repetitive surge energy without the wear-out mechanism of an RC snubber — it is sized for the coil energy of SIRIUS S00 contactors (3RT2.1 series) and auxiliary contactors (3RH2 series), so it suppresses the inductive kickback that would otherwise arc across the PLC output or relay contact driving the coil.
Clip-on mount — panel fit for S00 contactors
The clip-on fastening method means it snaps directly onto the front of the contactor without tools — no DIN-rail space consumed, no additional wiring. The 9 mm depth, 28 mm width, and 46 mm height match the S00 contactor footprint, so the suppressor sits flush within the contactor envelope.
