Product details

Rated for 3 hp at 230 V, it handles typical induction motors in that power class. The auxiliary contacts are rated 10 A at 24 V, 2 A at 48 V, and 0.9 A at 125 V — enough for pilot duty or PLC feedback in most line-voltage schemes.

The AC-3 switching rate of 750 operations per hour tells you this contactor is designed for motor starting under load — typical for conveyors, pumps, and compressors. If your application requires frequent reversing, watch that AC-4 ceiling. Wire range accepts solid or stranded 1 to 10 mm², and fine-stranded 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). That covers most motor and control wiring in a standard panel. The screw-type coil terminals are straightforward to terminate — no special tooling needed.

Clearances: 10 mm upwards, downwards, and forwards; 6 mm at the sides. That's tight enough for dense panel layouts — just keep the side gap for heat dissipation.

Frequently asked questions

What is the closest functional second-source — the 3RT2026-1AG20?

The 3RT2026-1AG20 is a peer in the same SIRIUS size S0 family, but the 3RT2026-1AK60-0UA0 includes an auxiliary switch and screw-type coil terminals. The 1AG20 variant may differ in coil voltage or auxiliary configuration — verify the coil rating and auxiliary contact count before substituting.

What are the key dimensions for panel layout?

Width is 45 mm, height 85 mm, depth 97 mm. Clearances: 10 mm upwards, downwards, and forwards; 6 mm at the sides.

What wire sizes does it accept?

Solid or stranded 1 to 10 mm². Fine-stranded: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Main contacts accept 16 to 8 AWG.
