It clips onto the contactor coil terminals to suppress the inductive voltage spike when the DC coil de-energises — without it, the back-EMF can arc across relay contacts or couple noise into adjacent control wiring. Rated for DC control supply voltages from 12 V to 250 V, it covers the common 24 VDC control loops found in most industrial panels, as well as higher-voltage DC bus applications up to 250 VDC. ## Mechanical fit — clips onto S00 contactors The suppressor uses a clip-on fastening method that snaps directly onto the contactor coil terminals — no wiring or additional hardware is needed. It mounts in any position, which simplifies layout in dense panels where orientation is constrained by wire routing or DIN-rail access. Dimensions are 9 mm depth, 28 mm width, and 46 mm height — the 9 mm depth means it adds negligible projection beyond the contactor face, keeping the panel fill factor tight. The S00 contactor size is the smallest frame in the SIRIUS range, so this suppressor is physically matched to that footprint. ## Active production and sourcing posture Sourced through authorised distribution channels against the BOM quantity. Availability and current pricing are confirmed at RFQ time — the landed cost depends on the shipment volume and destination Incoterms, so the quote reflects the full duty and freight picture, not just the unit price. ## Environmental limits and compliance Operating temperature range is -25 °C to +60 °C, with storage from -40 °C to +80 °C — the storage range is wide enough for unheated warehouses in most climates, while the operating range covers standard indoor panel environments without derating. The substance prohibition date of 10/01/2009 aligns with the original EU RoHS directive (RoHS 1) — the part is compliant with that cut-off, though current RoHS/REACH documentation should be confirmed against the latest revision at order time.","metaTitle":"Siemens 3RT2916-1DG00-ZX90 Surge Suppressor","metaDescription":"Siemens SIRIUS surge suppressor for contactors size S00.
