Product details

SIRIUS S00 Contactor, 24 VAC Coil, Spring-Type Terminals

The Siemens 3RT2518-2AB00 is a SIRIUS size S00 contactor with a 24 VAC 50/60 Hz coil and spring-type terminals on the magnet coil connection. The auxiliary switch is rated for switching at multiple voltage levels: 10 A at 24 V and 230 V, 2 A at 48 V, 60 V, and 125 V, 1 A at 110 V, 3 A at 400 V, 0.8 A at 440 V, 0.3 A at 220 V, and 0.1 A at 600 V. These ratings define the contact's switching capacity across control and auxiliary circuits. The contactor accepts solid or stranded conductors 2x (0.5... 4 mm²), with a depth of 73 mm and height of 70 mm.

Mounting and Environmental Range

The contactor is rated for 10 000 1/h switching at DC and up to 1 000 1/h at AC-1 maximum.

Frequently asked questions

How do I get current pricing and availability for 3RT2518-2AB00?

Submit an RFQ through the storefront. Pricing and stock are confirmed at quote time from independent distribution channels.

What is 3RT2518-2AB00's listed depth?

The depth is 73 mm.

What conductor sizes does the 3RT2518-2AB00 accept?

It accepts solid or stranded conductors 2x (0.5... 4 mm²).

Will 3RT2518-2AB00 drop into a panel specified around 3RT2526-1AD20 without rewiring?

No — the 3RT2526-1AD20 is a larger frame size with different current ratings and terminal spacing. The 3RT2518-2AB00 is size S00, while the 3RT2526 series is a larger frame. Panel cutouts and wiring will not directly interchange without modification.
