Product details

It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting a 45 mm wide footprint with a depth of 97 mm and height of 102 mm. An auxiliary switch is built in, rated for 10 A at 24 V and derating to 0.3 A at 220 V — enough for signaling back to a PLC or status lamp without an extra block.

Spring-type terminals accept solid or stranded wire from 1 to 10 mm², or two conductors of 0.5 to 2.5 mm² each. No screw torque to check — just strip and insert — which speeds wiring on repetitive builds.

Duty cycle and thermal limits

Rated for 1,000 switching operations per hour in AC-1, AC-2, AC-3, and AC-3e duty; AC-4 drops to 300 operations per hour due to the heavier electrical wear from inching and plugging cycles.

Frequently asked questions

How do I get current pricing and availability for 3RT2024-2AL20-1AA0?

Submit an RFQ through this listing; pricing and stock are confirmed at quote time through our independent distribution network.

What is the closest functional second-source to 3RT2024-2AL20-1AA0?

The 3RT2024-1AL20-ZX95 is a peer variant — same Size S0 footprint and spring-type terminals, but the -ZX95 suffix indicates a special version. Verify coil voltage and auxiliary contact configuration against your BOM before substituting.

Will 3RT2024-2AL20-1AA0 drop into a panel specified around 3RT2024-1AL20-ZX95 without rewiring?

Both are Size S0 with spring-type terminals and the same 45 mm width, so the mechanical fit and wiring should match. Confirm the auxiliary contact ratings and coil voltage match your control circuit — the -2AL20 variant includes a built-in auxiliary switch.

What compliance documentation does this brand provide for 3RT2024-2AL20-1AA0?

Siemens SIRIUS contactors typically carry CE, UL, CSA, and CCC certifications. Request the specific declaration of conformity and UL file number with your RFQ.
