Product details

Switching Duty & Mechanical Endurance

The 3RT2026-1AL20-ZW97: The contactor is rated for 750 cycles per hour in AC-3 and AC-3e duty, and 1,000 cycles per hour in AC-1 (resistive) duty. AC-4 (plugging/reversing) is limited to 250 cycles per hour.

The built-in auxiliary switch is rated at 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.6 A at 440 V.

These are the minimum air gaps for heat dissipation and arc containment — panel layout must respect them.

Frequently asked questions

What is the closest functional alternative to 3RT2026-1AL20-ZW97?

The closest peer is 3RT2026-1AG20, which shares the same Size S0 frame and DIN-rail footprint. The primary difference is the coil voltage — verify your control voltage before substituting.

What are the key dimensions of this contactor?

Width is 45 mm, height is 85 mm, and depth is 97 mm. It mounts on 35 mm DIN rail per DIN EN 60715.

What wire sizes does the main circuit accept?

Solid or stranded conductors from 1 to 10 mm². The coil terminals are screw-type.

Will 3RT2026-1AL20-ZW97 drop into a panel specified for 3RT2026-1AG20?

Yes, both are Size S0 contactors with the same 45 mm width and DIN-rail mounting. The panel cutout and wiring space are identical. Only the coil voltage differs — confirm that matches your control circuit.
