The Siemens SIRIUS 3RT2016-1CF07-ZX95 is a Size S00 power contactor with a 24 VDC magnet coil terminated via screw-type terminals. It mounts on a 35 mm DIN rail per DIN EN 60715 using either the snap-on or screw-fastening method, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward and backward — useful when panel layout is tight.
Key ratings and what they mean for fit
The contactor is rated for AC-1 switching at up to 1,000 operations per hour, AC-2 and AC-3 at 750 ops/h, and AC-4 at 250 ops/h. The AC-3e rating matches the 750 ops/h figure, so it handles standard motor starting duty without derating the cycle rate. Arcing time sits between 10 and 15 ms at 50/60 Hz, with a dropout time of 4 to 15 ms across the AC cycle — both figures govern how fast the load disconnects and how much energy the arc chute must absorb. Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, so it suits unheated enclosures in temperate climates as long as the panel stays above -25 °C. The 45 mm width and 117 mm depth keep the footprint compact for a Size S00 contactor, leaving room for auxiliary blocks or an overload relay on the same DIN rail.
Sourcing and lifecycle
The lifecycle stage is marked as current production, so this order code is still the active variant. No successor or phase-out notice is on record. For a BOM line that calls out the 24 VDC coil and screw terminals, this is the direct fit — no substitution needed. Availability and current pricing are confirmed at quote time against an RFQ through independent distribution channels.
