Product details

It carries three main NO contacts and is rated for 11 kW at 400 V in AC-2 duty (slip-ring motors) and 15.5 A in AC-4 duty (plugging/inching). The 24 VDC coil draws its holding current from a standard control supply; verify the free-wheel diode polarity if the coil is driven by a PLC output.

The 45 mm width and 85 mm height fit standard S0 panel layouts. Side-by-side mounting is permitted with zero lateral clearance, so no gap is needed between contactors on the rail. Screw-type terminals on the main circuit accept 2x (1... 2.5 mm²) stranded or 2x (2.5... 6 mm²) solid, up to 2x 10 mm² maximum. Auxiliary terminals handle 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²). The IP20 front-of-terminal protection means the contactor is safe for finger contact in a live panel; the terminal body itself is IP00, so it relies on the enclosure for environmental sealing.

Duty ratings and motor switching

The 11 kW rating at 400 V for AC-2 covers slip-ring motor starting where the contactor opens under load. The AC-4 rating of 15.5 A at 400 V is the limiting figure for reversing or inching duty — if your application requires frequent plugging, size the contactor on this number, not the AC-3 power. Auxiliary contact ratings cover the typical control-voltage range: 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC. The mechanical endurance of 10 million operations means the contactor outlasts most panel designs under normal switching frequencies.

The rated insulation voltage is 400 V at 50 Hz, with an operating altitude limit of 2000 m and ambient temperature range of -25 to +60 °C.

Frequently asked questions

How do I get current pricing and availability for 3RT1026-1AV00-1AA0?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; pricing and stock status are confirmed at quote time.

When sourcing 3RT1026-1AV00-1AA0, what's the closest functional alternative?

The 3RT1023-1AL20 is a smaller-frame SIRIUS contactor with a 24 VDC coil, but it is rated for lower motor power. The 3RT1026-1AB00 shares the same S0 frame and 3-pole configuration but uses an AC coil. The 3RT1016-1AG61 is a compact S00 frame for lighter loads. Only the 3RT1026-1AV00-1AA0 carries the 11 kW AC-2/AC-3 rating at 400 V with a 24 VDC coil in the S0 size.

Will 3RT1026-1AV00-1AA0 drop into a panel specified around 3RT1023-1AL20 without rewiring?

The 3RT1026-1AV00-1AA0 is a larger S0 frame (45 mm wide) versus the S00 frame of the 3RT1023-1AL20. The DIN rail mounting is the same, but the wider footprint and different terminal layout may require re-drilling the mounting plate and re-routing wires. The screw terminal cross-sections are similar, so existing wire gauges should fit, but panel space must be verified.
