Product Identification and Ratings
The Siemens SIRIUS 3RT1016-1AF02-1AA0 is a power contactor in frame size S00, designed for switching motor and resistive loads in industrial control panels. Its primary rating for resistive and general-purpose loads is 10 A at AC-12, which defines the continuous current it can carry in non-inductive circuits. For motor starting duty, it is rated 4 kW at AC-2 at 400 V, covering standard squirrel-cage motor start/run applications. For inching or plugging duty (AC-4), the rated operational current is 8.5 A at 400 V, which is the figure that governs contactor life under frequent switching.
Mounting and Integration
Mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 50022. The 45 mm width and 57.5 mm height allow side-by-side mounting without derating, per the manufacturer's specification. The front face carries an IP20 degree of protection, meaning the terminals are finger-safe when the panel door is open; the connection points themselves are also rated IP20. For panel builders, the screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors, with a maximum of 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16) and 2x (18 to 14).
Environmental and Coordination
Rated for an ambient operating temperature range of -25 to +60 °C, and suitable for installation at altitudes up to 2 000 m. The degree of pollution is 3, meaning it is rated for conductive pollution environments typical of industrial control panels. For short-circuit protection, with Type 2 coordination (no damage to the contactor) the required fuse is gL/gG 20 A; with Type 1 coordination (contactor may need replacement) the fuse rating is gL/gG 35 A. The auxiliary contact block integrated into this variant carries ratings of 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V, covering a wide range of control voltages.
