What this contactor is and what it does
The Siemens SIRIUS 3RT1316-2AN60 is a power contactor in the S00 frame size, designed for switching motor loads and resistive loads in control panels. Its four normally open (NO) main contacts are rated for 4 kW at 400 V in AC-2 duty, which covers slip-ring motor starting and plugging applications. The spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or stranded conductors, per the datasheet.
Mounting and integration
Mounts via screw or snap-on onto a 35 mm standard mounting rail per DIN EN 50022. The 45 mm width and 72 mm depth fit standard DIN-rail enclosures; side-by-side mounting is permitted without derating for the thermal conditions listed. Pollution degree 3 means it tolerates conductive pollution typical of industrial control cabinets.
Lifecycle and sourcing posture
This part carries a current production lifecycle status. For a BOM line or a replacement order, the 3RT1316-2AN60 is sourced to order against an RFQ. No official successor has been issued; the S00 frame and 4 NO configuration are current catalog items.
Key ratings and what they mean for fit
The 4 kW rating at 400 V AC-2 is the motor-switching capability under moderate overload conditions — relevant for slip-ring motors or applications requiring frequent reversing. The operating temperature range of -25 to +60 °C during operation covers most indoor industrial environments without forced cooling. The 10 A rated operational current at AC-12 (resistive load) at 24 V gives a reference for control-circuit switching.
