Active lifecycle, SIRIUS S00 fit
The 3RT2916-1JJ00-ZX90: The varistor-based design clamps voltage spikes from the contactor coil during de-energization, protecting nearby electronics and extending contact life. The integrated LED indicates the suppressor is operational.
Dual AC/DC voltage coverage
Rated for AC control supplies at 24-48V (50 Hz) and 48-24V (60 Hz), plus DC supplies at 12-24V. The AC/DC type means one part number covers both control voltage families — simplifies inventory for panels mixing AC and DC coils. Operating temperature range is -25 to +60°C, with storage from -40 to +80°C. The clip-on fastening method mounts directly onto the contactor or relay base without additional hardware.
Compact footprint for tight panels
Dimensions are 9 mm depth, 28 mm width, and 46 mm height — the narrow 9 mm profile fits into dense DIN-rail layouts where every millimeter matters. The mounting position is any orientation, so it works in horizontal or vertical rail runs. Multi-unit packaging (ZX90 suffix) means it ships in bulk quantities — relevant for OEM builds with consistent per-panel consumption.
