It snaps onto a 35 mm DIN rail per DIN EN 60715, occupying a 45 mm wide slot with a 121 mm depth — a standard panel footprint for motor switching up to 10 A at 24 VDC.
The 110 VDC coil is the primary selection gate — this contactor pulls in on a DC supply, not AC, so verify your control voltage before wiring. Size S00 means this is the smallest SIRIUS frame, suited for fractional-horsepower motors or resistive loads up to the rated switching capacity. The AC-4 maximum of 250 operations per hour sets the plugging/inching duty limit — exceed that and the contactor life drops fast. Storage tolerance down to -55 °C is a shipping/warehouse spec, not a running condition.
