Product details

Rated for 11 kW at 400 V in AC-2 duty (slip-ring motor starting), it handles 15.5 A in AC-4 (plugging/reversing/inching). For resistive AC-12 loads, the maximum operating current is 10 A. These ratings define the real switching capability: AC-2 covers the moderate inrush of wound-rotor motors, while AC-4 covers the severe duty of frequent reversing or jogging. Wire range for the main contacts accepts up to 2x 10 mm² stranded or 1x 8 AWG, with a solid range of 2x (0.5 to 1.5 mm²) for auxiliary circuits.

Side-by-side mounting is permitted with no gap, saving rail space. If you need clearance for airflow or wiring access, the required side spacing is 6 mm. Front protection is IP20 (finger-safe), while the terminal area is IP00 — meaning the connection points are live when the panel door is open. Pollution degree 3 (conductive pollution) is assumed, so the contactor is suited for industrial environments where occasional condensation or light dust is present. The rated operating voltage factor is 0.8 to 1.1 at 50 Hz and 0.85 to 1.1 at 60 Hz — meaning the coil holds in reliably even with a 20% voltage dip at 50 Hz.

For a BOM freeze or critical-spare holding, this is a low-risk line item.

Frequently asked questions

Where can I buy 3RT1026-1AN64 and what is the lead time?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the depth of 3RT1026-1AN64?

The depth is 140 mm, with a width of 45 mm and height of 85 mm.

What wire sizes does the 3RT1026-1AN64 accept?

Solid wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded main contacts: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG main: 2x (16 to 12), 2x (14 to 10), 1x 8.

What is the closest functional alternative to 3RT1026-1AN64?

The 3RT1023-1AL20 is a smaller-frame SIRIUS contactor with lower ratings. It will not drop into the same panel position without checking the mounting footprint and current capacity — the 3RT1026-1AN64 is the correct size S0 for 11 kW at 400 V AC-2.
