Product details

SIRIUS S0 power contactor — 3RT1023-3AN60

The Siemens 3RT1023-3AN60 is a SIRIUS S0 power contactor with screw-type terminals, rated for 4.5 kW at 500 V (50 Hz) and 5.5 kW at 690 V (60 Hz). Rated operational currents span 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 2 A at 60 V, covering a wide range of motor and resistive loads. The contactor also carries AC-4 switching capability at 8.5 A (400 V) for demanding reversing or inching duty.

Screw-type terminals accept 2x (0.25... 2.5 mm²) solid or stranded, plus 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²) for main circuits, with a maximum of 2x 10 mm². AWG equivalents: 2x (16... 12), 2x (14... 10), and 1x 8. The S0 frame width is 45 mm, height 85 mm, depth 90 mm — fits standard 45 mm-wide DIN-rail slots. For Type 2 coordination, a 25 A gL/gG fuse is required; for Type 1, a 63 A fuse.

Frequently asked questions

Where can I buy 3RT1023-3AN60 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is 3RT1023-3AN60's listed depth?

The depth is 90 mm, with a width of 45 mm and height of 85 mm — standard S0 frame dimensions.

What wire sizes does the screw terminal accept?

Main circuit terminals accept 2x (0.25... 2.5 mm²) solid or stranded, 2x (1... 2.5 mm²), 2x (2.5... 6 mm²), and up to 2x 10 mm². AWG equivalents: 2x (16... 12), 2x (14... 10), 1x 8.

Will 3RT1023-3AN60 drop into a panel specified for 3RT1023-1AL20 without rewiring?

Both are S0-frame contactors with the same mounting footprint (45 mm width, snap-on DIN rail) and screw-type terminals. The 3RT1023-3AN60 carries higher power ratings (4.5 kW at 500 V vs the 1AL20's lower ratings), so it is a functional upgrade in the same physical envelope — no rewiring of the DIN rail or terminal layout is required.

What compliance documentation does Siemens provide for 3RT1023-3AN60?

The part is designed to meet IEC/EN 60947-4-1 standards for contactors. Siemens typically provides RoHS and REACH declarations, along with UL/CSA certifications upon request. Specific documentation is confirmed at order.
