What it is and what it does
The Siemens 3RT2016-1AD02 is a SIRIUS power contactor in frame size S00, designed for switching motor loads and resistive loads in industrial control panels. It carries a 24 VDC coil with screw-type terminals, and includes an integrated auxiliary switch. The auxiliary contact is rated 10 A at 24 V, 2 A at 48 V, and 0.9 A at 125 V, covering typical PLC and relay interface signals. Switching frequency depends on duty class: up to 1 000 cycles/hour for AC-1 resistive loads, 750 cycles/hour for AC-3 motor starting, and 250 cycles/hour for AC-4 plugging/reversing.
Mounting and integration
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width and 58 mm height fit standard panel layouts; depth is 73 mm. Clearance requirements: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm to the side. Mounting position is flexible: ±180° rotation on a vertical surface, and can be tilted forward/backward by ±22.5° on a vertical surface. Terminals accept solid or stranded wire: 0.5 to 4 mm² single, or 2x 0.5 to 1.5 mm² / 2x 0.75 to 2.5 mm² / 2x 4 mm².
Environmental and lifecycle
Mechanical life is typical 30 000 000 operations. Arcing time is 10 to 15 ms, and operate time at AC is 4 to 15 ms.
