Product details

SIRIUS S0 power contactor — 3RT1023-3AT60

Rated for AC-3 duty at 4.5 kW at 500 V and 5.5 kW at 690 V, it handles typical three-phase induction motor loads in conveyor, pump, and fan applications. Front-side protection is IP20 (finger-safe), while the terminals themselves are IP00 — standard for screw-clamp contactors.

The 45 mm wide S0 footprint occupies a single DIN-rail position. Side-by-side mounting is permitted with zero clearance between units, saving rail space in dense panels. The 6 mm clearance to grounded metal on the side is the only mandatory air gap. Main circuit terminals accept screw-clamp connections: 2x (1–2.5 mm²) solid/stranded, 2x (2.5–6 mm²), or up to 2x 10 mm². AWG equivalents are 2x (16–12), 2x (14–10), or 1x 8. Auxiliary contact wiring uses 2x (0.25–2.5 mm²) solid.

For BOM freeze or second-source planning, the 3RT1023-3AT60 is a direct form-fit-function match for other S0-frame 3RT1023 variants with the same coil voltage. The screw-terminal main circuit and 3 NO contact configuration are the key fit parameters.

Type 2 coordination (contactor remains fully serviceable) requires a 25 A gL/gG fuse. These values guide the selection of branch circuit protection.

Frequently asked questions

What are the main contact ratings for 3RT1023-3AT60?

It has three normally-open main contacts. AC-3 motor power is 4.5 kW at 500 V and 5.5 kW at 690 V. AC-4 reversing duty is rated at 8.5 A at 400 V.

What is the coil voltage for this contactor?

The coil is rated at 24 VDC.

Where can I buy 3RT1023-3AT60 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.

Will 3RT1023-3AT60 drop into a panel specified around 3RT1023-1AL20?

Both are S0-frame contactors with the same 45 mm width and DIN-rail mounting, so the mechanical fit is identical. However, verify the coil voltage and main contact configuration match your circuit — the -3AT60 uses a 24 VDC coil and 3 NO main contacts.
