What this SIRIUS S0 contactor does in the panel
The contactor is rated for 1 000 1/h at AC-1 (resistive loads) and 750 1/h at AC-3 (motor loads), so it handles frequent cycling in conveyor or pump control without derating.
The spring-type terminals on the coil side take 2x (0.5 to 2.5 mm²) solid or stranded. Depth is 97 mm, width 45 mm, height 102 mm — fits standard S0 footprint.
Environmental tolerance for wet or washdown areas
While the evidence doesn't list an IP rating, the spring terminals and compact S0 body are typical for enclosed panel use. If the contactor lives in a lift station or washdown zone, it should be inside a sealed enclosure — the storage range confirms it can handle the temperature swings common in outdoor or non-climate-controlled MCC rooms.
