Product details

Rated 7.5 kW at both 500 V and 690 V (AC-3 duty), this contactor handles motor loads up to that power level in standard three-phase systems. For resistive loads (AC-12), it carries 10 A continuously. The 50 Hz coil operates at 0.8 to 1.1 times rated voltage, so it pulls in reliably even on a soft supply. Size S0 means a 45 mm wide footprint — three of these fit in a standard 145 mm DIN section. Depth is 90 mm, which clears most shallow enclosures.

Mounting and wiring notes

Screw terminals accept up to 2x 10 mm² solid or stranded, or 2x 2.5 mm² with ferrule. AWG equivalents: 2x 16–12, 2x 14–10, or 1x 8. Side-by-side mounting is allowed — no derating required for adjacent units. Pollution degree 3 means it tolerates conductive dust and humidity typical of industrial control panels.

Frequently asked questions

Where can I buy 3RT1024-3AH00?

We source and quote this part to order against an RFQ. Availability and current pricing are confirmed at quote time.

Will 3RT1024-3AH00 drop into a panel that was specified around 3RT1023-1AL20 without rewiring?

Both are S0 frame contactors with the same 45 mm width and screw terminals, so physical fit and mounting are identical. However, the 3RT1023-1AL20 has a different coil voltage and rating — verify the coil voltage matches your control circuit before swapping.

What compliance documentation does Siemens provide for 3RT1024-3AH00?

As a SIRIUS product, it carries CE marking and is designed to meet relevant IEC/EN standards. Specific RoHS, REACH, and UL documentation is available on request from the manufacturer or through our sourcing desk.
