Product details

The 3RT1023-3AG60: The AC-4 rating of 8.5 A at 400 V is the figure to size by if your motor cycles on-off repeatedly, reverses, or plugs — those operations stress the contacts more than steady running. For across-the-line starting of cage motors (AC-3) you'd use the higher current capability implicit in the AC-2/AC-4 mix; the 4 kW AC-2 rating at 400 V covers slip-ring motor duty. For Type 1 coordination (contactor may need replacement after fault) the fuse can go up to 63 A.

Side-by-side mounting is permitted — no derating gap required. The front face carries IP20 protection; the terminals themselves are rated IP00, so panel builders should allow clearance around live parts.

Frequently asked questions

Where can I buy 3RT1023-3AG60 and what is the lead time?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time — submit an RFQ for the real ETA.

What is 3RT1023-3AG60's AC-4 current rating at 400 V?

8.5 A in AC-4 duty at 400 V — that's the rating for frequent starting, reversing, or inching cycles.

What fuse size is required for Type 2 coordination on 3RT1023-3AG60?

Siemens specifies a gL/gG fuse of 25 A for Type 2 coordination (no damage to the contactor on short circuit). For Type 1 coordination, the fuse can be up to 63 A.

Will 3RT1023-3AG60 drop into a panel specified around 3RT1023-1AL20?

Both are S0 frame size on 45 mm width with screw terminals and DIN-rail mount, so the physical footprint and wiring method are the same. The key difference is the coil voltage — 3RT1023-3AG60 uses a 100-110 V 50/60 Hz coil, while 3RT1023-1AL20 uses a different coil voltage. Verify the control voltage matches your circuit before substituting.
