Product details

SIRIUS 3RT2024-2AF00 — Power Contactor, Size S0, 24 VDC Coil

It includes an integrated auxiliary switch (1 NO + 1 NC, 18...8 A for main contacts). The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a width of 45 mm, height 102 mm, and depth 97 mm — a compact footprint for the S0 frame. Auxiliary contact ratings span from 10 A at 24 V down to 0.3 A at 220 V, covering typical control-circuit loads across common DC and AC voltages. The contactor is rated for up to 1,000 switching cycles per hour under AC-1, AC-2, AC-3, and AC-3e duty, and 300 cycles/h under AC-4 — suitable for frequent motor starting and stopping in conveyor, pump, and fan applications.

Panel Integration & Wiring

The contactor accepts solid or stranded conductors from 1 to 10 mm² on the main terminals, and 2x (0.5...2.5 mm²) on the auxiliary terminals. Spring-type terminals eliminate the need for screwdriver torque checks — strip length and insertion depth are the only variables. Minimum clearances: 10 mm upwards, downwards, and forwards; 6 mm at the sides.

Frequently asked questions

How do I get current pricing and availability for 3RT2024-2AF00?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time against current market availability; no firm figures are published here.

Will 3RT2024-2AF00 drop into a panel that was specified around 3RT2016-1AG62 without rewiring?

Both are SIRIUS power contactors in size S0 with spring-type terminals and 24 VDC coils, so the footprint and terminal layout are identical. No rewiring is needed for the main or auxiliary connections — the 3RT2024-2AF00 is a direct mechanical and electrical replacement for the 3RT2016-1AG62 in the same panel.

What compliance documentation does this brand provide for 3RT2024-2AF00 (RoHS, REACH, UL, IEC)?

As a Siemens SIRIUS product, the contactor is designed to meet IEC/EN 60947-4-1 and relevant UL/CSA standards. RoHS and REACH declarations are available from Siemens upon request; the specific certifications for this order code are confirmed at time of order.
