Product details

The 24 VDC coil draws 10 A at rated voltage, with a pick-up dropout range of 0.85 to 1.1 times the rated value. At 45 mm wide, 57.5 mm tall, and 72 mm deep, this contactor fits standard panel layouts and allows side-by-side mounting without derating in ambient temperatures from -25 to +60 °C.

The DC switching ratings tell you what inductive loads this contactor can break. At 24 V it handles 10 A, at 60 V it drops to 2 A, at 110 V it's 1 A, and at 220 V it's 0.3 A. These are the maximum currents for DC-13 duty (solenoid/brake loads) — the arcing time of 10 to 15 ms and the dropout delay of 7 to 10 ms are the mechanical response you need for timing coordination in safety circuits. The screw terminals accept 2x 0.5 to 1.5 mm² solid or 2x 0.75 to 2.5 mm² stranded, up to 4 mm² maximum.

Frequently asked questions

What are the key ratings for this contactor?

The 24 VDC coil draws 10 A. DC switching capacity is 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. Auxiliary contacts are rated 12 A each. The contactor measures 45 x 57.5 x 72 mm and mounts on 35 mm DIN rail.

What compliance documentation is available for the 3RT1517-1BG40?

As a Siemens SIRIUS product, it carries CE marking and is designed to IEC/EN 60947 standards. Specific RoHS and REACH declarations are available through the Siemens Industry Online Support portal.
