Product details

Siemens SIRIUS 3RT1517-1AH00 — Size S00 power contactor for 24 VDC coil control

The Siemens SIRIUS 3RT1517-1AH00 is a size S00 power contactor rated for 24 VDC coil control, switching 10 A at 24 V rated value.

The 10 A rating at 24 V rated value is the DC-13 switching current for the main contacts — that's the inductive load capability for solenoids, brakes, or DC motor holding coils at 24 VDC. Wire termination accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded, up to 2x (0.75 to 4 mm²) maximum — this covers standard control wiring for a size S00 contactor. The screw terminals need a screwdriver for termination, not a spring-cage tool. Mechanical life is typical 30,000,000 operations, which is standard for a SIRIUS S00 contactor in cyclic applications like conveyor or packaging machine control.

The mounting position allows vertical surface orientation with ±180° rotation and ±30° tilt front/back, which covers most cabinet layouts. IP20 on the front and terminals means finger-safe but not washdown — this is for dry indoor panels only, not food-processing or outdoor enclosures without a cabinet.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, height 57.5 mm, depth 72 mm. It mounts on 35 mm DIN rail and allows side-by-side mounting without gaps.

What wire sizes does the screw terminal accept?

Solid or stranded: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), maximum 2x (0.75 to 4 mm²).

What is the coil voltage and switching current?

24 VDC coil. At 24 V rated value the main contacts switch 10 A. For AC loads: 6 A at 230 V, 3 A at 400 V.

How does it compare to the 3RT1016-2AP02?

Both are Siemens SIRIUS size S00 contactors with similar DIN footprint, but the 3RT1016-2AP02 uses a 24 VAC/DC coil with spring-cage terminals, while the 3RT1517-1AH00 uses a 24 VDC coil with screw terminals. The 3RT1517-1AH00 has a 10 A DC-13 rating at 24 V; the 3RT1016-2AP02 has different coil draw and terminal style. They are not direct drop-in replacements without checking coil supply and wiring method.
