Product identity and key ratings
The Siemens 3RT1016-1AN62 is a SIRIUS power contactor in frame size S00, designed for switching motor loads in industrial control panels. Its main contact is rated 10 A at 24 V, and for AC-2 duty (slip-ring motor starting) it delivers 4 kW at 400 V. For AC-4 duty (inching, plugging, reversing) the rated operating current is 8.5 A at 400 V — this is the figure that governs frequent, high-stress switching cycles, not the thermal current.
Mounting and integration
Mounts via screw and snap-on onto a 35 mm standard mounting rail per DIN EN 50022. The S00 footprint is 45 mm wide, 57.5 mm high, and 72 mm deep — a compact envelope that leaves room for auxiliary contact blocks on the side. Side-by-side mounting is permitted, with a minimum 6 mm clearance to adjacent devices for heat dissipation. The front and terminal areas are rated IP20, meaning finger-safe but not protected against moisture ingress; this contactor is intended for dry, enclosed panel environments.
Environmental and coordination
Rated for an operating temperature range of -25 to +60 °C, with degree of pollution 3 — suitable for industrial atmospheres with conductive dust or occasional condensation. For short-circuit protection, type 2 coordination (no damage to the contactor) requires a gL/gG fuse rated 20 A; type 1 coordination (contactor may need replacement) allows a 35 A fuse. The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max. 2x (0.75 to 4 mm²) solid or stranded conductors.
