Product details

Terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with finely stranded wire requiring core-end ferrules.

AC-3 motor switching and coil draw

The AC-4 rating is lower at 250 cycles per hour, which governs plugging and inching applications. The DC coil draws 0.82 W during closing and holds at 0.24 W — a low holding power that keeps heat rise minimal in a dense panel. The auxiliary switch extension is supported (product extension auxiliary switch: Yes), so you can add a side-mount block without changing the contactor footprint. Contact reliability is specified for PLC-level signals (17 V, 5 mA), meaning the auxiliary contacts can switch low-energy logic inputs without stiction.

Pollution degree 3 (industrial environment). Shock resistance is 12.5g for 5 ms and 7.8g for 10 ms on the AC sine pulse. The part carries no NC main contacts; all three poles are NO.

Frequently asked questions

Will 3RT7026-1AP05 drop into a panel specified for 3RT6026-1AN20 without rewiring?

Both are S0-size contactors with the same 55 mm width and 35 mm DIN rail mounting, so the mechanical footprint and terminal layout are identical. The main difference is the coil type — the 3RT7026-1AP05 uses a DC coil; if the existing panel wiring and control voltage match DC, it drops in without rewiring.

What compliance documentation does Siemens provide for 3RT7026-1AP05?

The part carries IP20 finger-safe protection on front and terminals, pollution degree 3 rating, and surge voltage resistance of 6 kV. Standard Siemens documentation includes a CE declaration of conformity and RoHS/REACH compliance statements available on request.
