Product details

The Siemens 3RT1024-3AK60 is a SIRIUS S0 power contactor rated for motor switching at 5.5 kW at 400 V AC-3 duty and 7.5 kW at 500 V and 690 V. The 24 VDC coil pulls in across 0.8 to 1.1 times rated voltage at both 50 Hz and 60 Hz. It carries 10 A at 24 VDC on the auxiliary contacts and 2 A at 60 VDC.

Size S0 means 45 mm wide, 85 mm tall, 90 mm deep — fits the standard 35 mm DIN rail per EN 50022 and accepts screw-and-snap mounting. Side-by-side mounting is supported with only 6 mm spacing required between contactors. The main power circuit uses screw-type terminals; the auxiliary and control circuit uses spring-loaded terminals.

For Type 1 coordination (contactor may need replacement), a 63 A gL/gG fuse is required.

The contactor carries an IEC 81346-2 reference code of Q (switching device).

Frequently asked questions

Where can I buy 3RT1024-3AK60 and how is it quoted?

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

What is the closest functional alternative to 3RT1024-3AK60?

The 3RT1026-1AB00 is a sibling in the same SIRIUS S0 frame but with a different coil voltage and terminal configuration — verify coil voltage and terminal style before substituting.

Will 3RT1024-3AK60 drop into a panel designed for 3RT1026-1AB00?

Both are S0 size with the same 45 mm width and DIN rail mounting, so the footprint is identical. The difference is the coil voltage and terminal type — check those before swapping.

What compliance documentation does Siemens provide for 3RT1024-3AK60?

As a SIRIUS component, it carries CE marking for the European market. Specific UL, RoHS, and REACH declarations are available from Siemens documentation for this order code.
