Siemens 3RT2016-2BG42 — SIRIUS Power Contactor, Size S00
The Siemens 3RT2016-2BG42 is a SIRIUS power contactor in size S00, designed for switching motor loads and resistive circuits in industrial control panels. It carries a 24 VDC coil and spring-type terminals for tool-free wiring of solid or stranded conductors from 0.5 to 4 mm². At 24 V rated value the main contacts switch 10 A; at 400 V rated value the contactor handles 3 A. The auxiliary switch is built in, so no separate add-on block is required for basic status feedback. Mounting is screw or snap-on onto 35 mm standard rail per DIN EN 60715. The 45 mm width and 73 mm depth keep panel density tight — three units fit in a 145 mm wide DIN section with room for a terminal block.
Integration & Clearance
Minimum clearances to adjacent components: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward or backward, which covers most panel layouts without derating. Operating temperature range is -25 to +60 °C; storage range -55 to +80 °C. The contactor is rated for 30 million mechanical operations typical, with maximum switching rates of 1000 cycles/hour at AC-1 and 750 cycles/hour at AC-3.
