SIRIUS Size S00 power contactor — 3RT1016-2AN61
The Siemens 3RT1016-2AN61 is a SIRIUS power contactor in the compact Size S00 frame, rated for motor switching up to 5.5 kW at 690 V and 4.5 kW at 500 V. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded conductors, matching the wiring practice on a typical DIN-rail panel.
At 400 V AC-2 duty the contactor handles 4 kW, and at AC-4 (reversing or inching) it is rated 8.5 A — the AC-4 figure is the one that governs frequent jogging or plugging applications. The 24 V rated current of 10 A covers the control-circuit side; at 60 V it drops to 2 A, and at 220 V to 0.3 A, so verify the coil-supply voltage against the load curve. For type 2 coordination (no-weld protection) the required upstream fuse is 20 A gL/gG; for type 1 coordination (welding allowed but no fire hazard) it is 35 A gL/gG. Pollution degree 3 and IP20 on the front mean the contactor is suited for conventional control panels, not sealed washdown environments.
Side-by-side mounting is permitted with zero clearance — no extra spacing needed between units. The 73 mm depth and 60 mm height keep the footprint compact.
