Product details

Acceptable solid and stranded conductors from 1 to 10 mm², with twin-wire capacity for 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²).

Marked as current in the product lifecycle stage — no end-of-life notice or last-time-buy schedule. Available through standard distribution; quote to order. Operating temperature range -25…+60 °C, storage -55…+80 °C, covering most panel environments.

Comparison Note: 3RT2026-1AG20

Both parts share the S0 frame, 45 mm width, and DIN rail mount. Verify coil voltage and auxiliary contact complement before substitution.

Frequently asked questions

What is the depth of this contactor?

141 mm.

What solid wire sizes are accepted?

1 to 10 mm² solid or stranded. Also accepts two wires per terminal in specified combinations.

Will the 3RT2025-1AK64-3MA0 drop into a panel designed for the 3RT2026-1AG20?

Both are S0 frame parts with the same 45 mm width and DIN rail mount, but the coil voltage and auxiliary contact arrangement may differ. Verify those specs on your existing 3RT2026-1AG20 before swapping.
