It suppresses voltage spikes across the coil terminals when the contactor de-energises, protecting the control circuit and extending contact life on inductive loads. Rated for 240-400 V AC at both 50 Hz and 60 Hz, it covers the common control-voltage range across European and North American panels. The varistor clamps the transient voltage to a safe level, preventing coil-driver damage on PLC outputs or relay contacts. ## DIN-rail footprint and clip-on fit At 30 mm wide, 19 mm tall, and 12 mm deep, this suppressor adds negligible depth to the contactor assembly. The clip-on fastening method means it snaps directly onto the contactor's coil terminals — no extra DIN-rail space consumed, no wiring changes needed. Mounting position is any orientation, so it fits in tight enclosures where vertical or horizontal contactor banks are used. Operating temperature range is -25 to +60 °C, with storage from -40 to +80 °C — fine for most control-panel environments. ## Active lifecycle and sourcing position The part is sourced through independent distribution against an RFQ.","metaTitle":"Siemens 3RT2926-1BE00 SIRIUS Surge Suppressor, Varistor","metaDescription":"Siemens 3RT2926-1BE00 SIRIUS surge suppressor, varistor type, rated 240-400V AC 50/60 Hz.
