Product details

It's rated for AC-4 switching duty at 12.5 A at 400 V — that's the category for reversing or inching motor starts where the contactor makes and breaks stalled-rotor current, so the contacts take a harder hit than a standard AC-3 run contactor.

Sizing and Coordination

For Type 2 coordination (contactor remains fully operational after a short, no contact welding), the fuse drops to gL/gG 25 A. That's the spec to hand your panel builder when they're sizing the branch circuit protection. That's the mechanism itself — electrical life will be lower and depends on the switching category and load current. For a contactor that's seeing frequent inching or reversing (AC-4), expect the electrical endurance to be a fraction of that mechanical figure.

Main circuit screw terminals accept 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), or max 2x 10 mm² solid/stranded, with AWG equivalents of 2x (16 to 12), 2x (14 to 10), or 1x 8. Auxiliary control circuit terminals take 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²), with AWG 2x (20 to 16), 2x (18 to 14), or 1x 12. That covers most panel wire gauges you'd run to a contactor coil and aux contacts.

Frequently asked questions

How do I get current pricing and availability for 3RT1024-1AP04-1AA0?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.

What is 3RT1024-1AP04-1AA0's listed depth?

The depth is 140 mm, with a width of 45 mm and height of 85 mm.

Will 3RT1024-1AP04-1AA0 drop into a panel specified around 3RT1026-1AB00 without rewiring?

Both are size S0 frame contactors with the same 45 mm width and DIN-rail mounting, so the footprint is the same. But the 3RT1026-1AB00 is a higher-current variant — verify your load rating before swapping down. Terminal layout and screw-type connections are consistent across the S0 frame.

What compliance documentation does Siemens provide for 3RT1024-1AP04-1AA0?

The part carries a substance prohibition date of July 1, 2006, aligning with RoHS compliance. The reference code per IEC 81346-2 is Q. Standard Siemens declarations of conformity for IEC/EN 60947 series apply.
