It clips onto the contactor, occupying a 30 mm width and 14.5 mm depth on the DIN rail — a compact footprint that leaves room alongside other control gear in a high-density panel. ## Voltage range and coil protection Rated for 240–400 V AC at 50 Hz and 400–240 V AC at 60 Hz, this RC snubber suppresses inductive voltage spikes from the contactor coil each time it de-energizes. Without it, the collapsing field can couple noise into nearby electronics or cause premature contact erosion. The RC element is a passive, polarity-independent solution — no diode to orient, no varistor to derate. ## Mounting and thermal range Clip-on fastening to the S2 contactor body; no separate DIN-rail slot needed. Mounting position is any, which helps when the contactor is installed sideways in a shallow enclosure.","metaTitle":"Siemens 3RT2936-1CE00 SIRIUS Surge Suppressor, RC Element, 2","metaDescription":"Siemens SIRIUS 3RT2936-1CE00 surge suppressor, RC element for contactors 3RT2.3.
