Product details

The Siemens SIRIUS 3RT1517-1BW40 is a size S00 power contactor with a 24 VDC coil, rated for switching DC loads up to 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 0.8 A at 440 V. Screw-type terminals on the main circuit accept 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), or max. 2x (0.75... 4 mm²) solid or stranded wire. The auxiliary contacts (1 NO + 1 NC) are each rated 12 A continuous.

Duty and switching performance

The DC switching ratings shown above are for resistive loads; inductive loads will require derating or arc-suppression. In AC-1 duty (resistive), the maximum switching rate is 1 000 operations per hour. The mechanical life is typical 30 million operations.

The mounting surface can be vertical with the contactor rotated ±180° or tilted ±30° front/back.
