SIRIUS Size S00 Power Contactor, 24 VDC Coil
The Siemens 3RT2016-1BB41-ZX95 is a SIRIUS power contactor in frame size S00, rated for 24 VDC coil voltage with screw-type terminals. It handles AC-3 motor switching at up to 750 operations per hour and delivers a mechanical life of 30,000,000 cycles typical. The 24 VDC coil picks up at 0.8 x rated voltage and drops out at 1.1 x rated voltage, with a DC switching time of 7 to 13 ms and arcing time of 10 to 15 ms. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, occupying 45 mm width, 58 mm height, and 73 mm depth. Clearance requirements: 10 mm upwards, downwards, and forwards; 6 mm at the side. Operating temperature range is -25 to +60 °C; storage from -55 to +80 °C.
Wiring and Terminal Specs
Screw-type terminals accept solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². Main contacts are sized for wire range 20 to 12 AWG. An auxiliary switch is included on the contactor.
Switching Duty and Auxiliary Ratings
Maximum switching frequency varies by duty: AC-1 (resistive) at 1,000 operations/hour; AC-2 and AC-3 (motor starting) at 750 operations/hour; AC-4 (plugging/inching) at 250 operations/hour. AC-3e (enhanced motor) also rated at 750 operations/hour. Auxiliary contact ratings: 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, and 3 A at 400 V. Motor horsepower rating: 1 hp at 230 V.
Mounting and Panel Integration
Fastening method is screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715. Mounting position is flexible: +/-180° rotation possible on a vertical mounting surface; can be tilted forward and backward by +/- 22.5° on a vertical mounting surface. The S00 frame size keeps the footprint compact for dense panel layouts.
