Product details

The Siemens SIRIUS 3RT2026-1NB30 is a Size S0 power contactor with a 24 VDC coil, screw-type terminals, and a rated operational current of 10 A at 24 V. The contactor includes an auxiliary switch and is rated for a mechanical life of 10,000,000 operating cycles.

Maximum switching frequency varies by duty: AC-1 (resistive) at 1000 cycles/h, AC-2 and AC-3 (motor starting/running) at 750 cycles/h, AC-4 (plugging/inching) at 250 cycles/h. The AC-3e rating also caps at 750 cycles/h. Operating time for both AC and DC coils is 30 to 50 ms; arcing time is 10 ms.

Coil and Auxiliary Ratings

The coil is rated 21 to 28 VDC with an inrush current peak of 3 A. At 24 V the rated current is 10 A; at 48 V and 60 V it drops to 2 A; at 110 V it is 1 A. The auxiliary switch accepts wire sizes 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
