Integrator's Quick Spec
The Siemens SIRIUS 3RT1016-2HB41 is a size S00 power contactor with a 24 VDC coil, rated for 10 A in AC-12 duty. It uses spring-loaded terminals on both main and auxiliary/control circuits, accepting 2x (0.25... 2.5 mm²) solid or stranded wire. The coil holds at 2.3 W DC, with no dropout voltage given — expect release around 18 V or lower. Mounts via screw or snap-on to 35 mm DIN rail per EN 50022, and can be mounted side-by-side without derating.
Ratings & Coordination
Motor switching capability: 4 kW at AC-2 / 400 V, and 8.5 A at AC-4 / 400 V. For general resistive loads (AC-12), the maximum operational current is 10 A. Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination needs a 20 A gL/gG fuse. Pollution degree 3 rating means it's suitable for industrial environments with conductive contamination.
Panel Integration
Dimensions: 45 mm wide, 60 mm high, 73 mm deep. Spring-clamp terminals on main and auxiliary circuits. 24 VDC coil draws 2.3 W holding.
