Product details

It's rated for 11 kW at 500 V and 11 kW at 690 V in AC-3 duty, and handles 15.5 A in AC-4 (reversing/inching) service. Screw terminals on both the main and auxiliary/control circuits — field-serviceable, no special crimp tool required.

RoHS compliance date is 01.07.2006, so it meets the EU substance restrictions that matter for CE-marked panels.

For type 1 coordination (no downstream damage on a short), the upstream fuse can be 100 A gL/gG; for type 2 (contactor must still function after clearing), it's 35 A gL/gG. That's the selectivity headroom you need for a coordinated panel.

Frequently asked questions

What is the 3RT1026-1AK60 used for?

It's a power contactor for switching three-phase induction motors in industrial control panels — conveyors, pumps, fans, compressors — up to 11 kW at 500 V or 690 V AC-3.

Where can I buy the 3RT1026-1AK60?

Sourced and quoted to order through independent industrial-automation distribution. Submit an RFQ for current availability and pricing.

Will the 3RT1026-1AK60 drop into a panel wired for the 3RT1026-1AB00?

Both are S0 frame, same footprint and screw-terminal layout, so the mechanical fit and wiring pattern are identical. The difference is in the coil voltage — the -1AK60 uses a different control voltage than the -1AB00. Verify your control circuit voltage before swapping.

What compliance documentation does this contactor carry?

RoHS compliant as of 01.07.2006, pollution degree 3 per IEC 60947, and designed to IEC 60947-4-1 for contactors and motor starters.
