SIRIUS size S00 contactor with spring terminals
The Siemens 3RT2016-2EP02 is a SIRIUS power contactor in the size S00 frame, designed for switching loads up to 10 A at 24 V rated value. The coil is 24 VDC with spring-type terminals, so no screwdriver needed for the coil wiring — just strip and push. The main contacts use screw terminals accepting 0.5 to 4 mm² solid or stranded wire, with a solid or stranded rating of 2x (0.5 to 4 mm²) per clamp. This is the variant you grab when the panel spec calls for spring-clamp coil connections and a compact 45 mm wide footprint.
Mounting and panel fit
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width and 117 mm depth mean it fits standard S00 contactor spacing on the rail. Mounting position is flexible: +/-180° rotation on a vertical surface, and can be tilted forward/backward by +/-22.5° on a vertical surface. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. That 6 mm side gap is tighter than some other S00 contactors — check your gland plate layout if you're packing multiple units side-by-side.
Switching ratings and duty cycles
Rated operational current varies by voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.2 A at 440 V. At 230 V it carries a 1 hp motor rating. Maximum switching frequency depends on duty: 1 000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting), 250 cycles/hour at AC-4 (plugging/inching). Arcing time is 10 to 15 ms at AC. The mechanical life is typical 30 million operations. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
