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.
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. DC coil dropout delay spans 38–65 ms — factor this into control logic timing.
