Product details

SIRIUS 3RT2518-2AP00 — Size S00 Contactor, 24 VDC Coil

The Siemens SIRIUS 3RT2518-2AP00 is a size S00 contactor with a 24 VDC coil, rated to switch 10 A at 24 V and 10 A at 230 V. The 45 mm width and 73 mm depth fit the standard S00 footprint on 35 mm DIN rail per DIN EN 50022.

Switching Ratings and Duty

The contactor's AC-1 maximum switching frequency is 1,000 1/h, and the DC switching frequency reaches 10,000 1/h. Arcing time sits at 10 to 15 ms. For auxiliary switching, the contactor carries an auxiliary switch. Rated operational current varies by voltage: 10 A at 24 V, 10 A at 230 V, 3 A at 400 V, and 0.1 A at 600 V. These ratings cover motor starting and resistive loads within the S00 frame.

Mounting and Environmental

Frequently asked questions

What is 3RT2518-2AP00's depth and width?

The depth is 73 mm and the width is 45 mm.

What wire sizes does the spring terminal accept?

The spring-type terminals accept 2x (0.5 to 4 mm²) solid or stranded wire.

Where can I buy 3RT2518-2AP00?

This part is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

Will 3RT2518-2AP00 drop into a panel specified around 3RT2526-1AD20?

The 3RT2518-2AP00 is a size S00 contactor, while the 3RT2526-1AD20 is a larger frame. Panel fit and wiring differ; verify footprint and terminal spacing before substitution.
