It suppresses voltage spikes from the coil circuit when the contactor de-energises, protecting nearby electronics and extending contact life. ## Voltage coverage and supply type Rated for AC 24-48V at 50 Hz and DC 24-70V, it handles both control supply types with a single unit. The AC/DC designation means you can run it off either rail without swapping parts. At 60 Hz the rated range is 48-24V — note the reversed order, which is how the manufacturer lists it. The part covers the same 24-48V window regardless of line frequency. ## Mechanical fit and panel integration Clip-on fastening to the contactor front, no DIN rail footprint needed. The 12 mm depth, 30 mm width, and 19 mm height keep it inside the contactor envelope, so it doesn't eat panel space. Mounting position is any — no derating required for horizontal or inverted orientation. Operating temperature range is -25 to +60 °C, storage -40 to +80 °C. ## Lifecycle and sourcing posture Sourced to order against the BOM quantity through independent distribution.","metaTitle":"Siemens 3RT2926-1CB00-ZX90 Surge Suppressor, RC, S0 Size","metaDescription":"Active-production Siemens SIRIUS surge suppressor for S0 contactors.
