SIRIUS coupling contactor, size S00 — 24 VDC coil, 10 A
The Siemens 3RT2016-1JB41 is a SIRIUS coupling contactor in the compact size S00 frame, designed for switching loads in control panels where space is tight — 45 mm wide, 58 mm tall, 73 mm deep. The 24 VDC magnet coil with screw-type terminals pulls in at 0.7 of rated voltage and holds reliably across the -25 to +60 °C operating range. Rated operational current at 24 VDC is 10 A, with a maximum switching frequency of 750 cycles per hour under AC-3 motor duty.
Mounting and integration
Mounts via screw or snap-on onto standard 35 mm DIN rail per DIN EN 60715. The mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° forward/backward tilt — useful when fitting into crowded enclosures. Minimum clearance: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the side. Accepts solid or stranded wire from 0.5 to 4 mm², with dual-wire capacity up to 2× 2.5 mm².
Switching frequency by duty class
Maximum switching rates vary by load type: 1 000 cycles/hour for AC-1 resistive loads, 750 cycles/hour for AC-2 and AC-3 motor duty, 250 cycles/hour for AC-4 (plugging/reversing). The AC-3e rating also permits 750 cycles/hour. Arcing time is 10–15 ms; DC coil dropout delay spans 38–65 ms — factor this into control logic timing.
