The clip-on fastening means it snaps onto the contactor without additional wiring or panel space; the overall dimensions are 12 mm deep, 30 mm wide, and 19 mm high, so it adds negligible footprint inside the enclosure. The 3RT7926-1BE00 is listed as current production. The part carries a RoHS compliance date of 06/15/2022, covering the EU directive. Clip-on mounting to the S0 contactor frame — no tools, no DIN-rail slot consumed. Any mounting position is allowed, which simplifies layout in dense panels. The varistor design means it absorbs the energy from the coil's inductive kick, extending contactor life and reducing EMI.","metaTitle":"Siemens 3RT7926-1BE00 SIRIUS Surge Suppressor, Varistor, 240","metaDescription":"Siemens 3RT7926-1BE00 SIRIUS varistor surge suppressor for S0 contactors.
