SIRIUS 3RT2016-2BB41-ZW96 — 24 VDC Coil Power Contactor, Size S00
The Siemens 3RT2016-2BB41-ZW96 is a SIRIUS power contactor in size S00, rated for a 24 VDC coil and fitted with spring-type terminals for the magnet coil. It switches up to 10 A at 24 VDC and 3 A at 400 VAC, with a mechanical endurance typical of 30,000,000 operating cycles. The contactor mounts on a 35 mm DIN rail per DIN EN 60715, with a width of 45 mm, height of 70 mm, and depth of 73 mm — a compact footprint for panel integration.
Ratings and What They Mean for Fit
The 10 A rating at 24 VDC is the DC-1 resistive load current — the contactor handles DC loads up to that level, but for inductive DC loads (DC-13) the rating drops significantly. At 48 VDC it is rated 2 A, and at 125 VDC only 0.9 A, so for a motor brake or solenoid valve on a 24 VDC bus, the 10 A figure is the one that governs fit. The 3 A at 400 VAC covers small three-phase motor loads in AC-3 duty (squirrel-cage motors starting and disconnecting under load), with a maximum switching frequency of 750 operations per hour in AC-3. The 1 hp rating at 230 VAC confirms its use on fractional-horsepower single-phase motors.
Mounting and Wiring
The contactor accepts solid or stranded wire from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) for paralleled conductors. Spring-type terminals on the coil save wiring time — no screw torque to verify. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, so it fits odd panel orientations. Clearance requirements: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side. The DC operating time (7 to 13 ms) and arcing time (10 to 15 ms) matter for coordination with upstream protection — the contactor clears faults within that window.
