Product details

The Siemens 3RT2026-4AK60 is a SIRIUS power contactor in size S0, rated for 21 A at 480 V in AC-3 duty — that's the motor-switching current, so it handles a 3-phase induction motor up to roughly 15 hp at 480 V. It carries an auxiliary switch on board, so you don't need a separate block for basic status feedback. The coil connection uses a ring cable lug, which is standard for panel wiring.

The 45 mm width fits a standard 9 mm pitch panel — that's five slots. Depth is 97 mm, height 85 mm.

Sourcing and compliance

This is a current-production Siemens SIRIUS contactor.

Frequently asked questions

What is the closest functional second-source for 3RT2026-4AK60?

The 3RT2015-4AN62 is a size S0 SIRIUS contactor in the same family, but it has a lower AC-3 rating (9 A at 400 V vs 21 A at 480 V). It will not drop into a panel specified for the 3RT2026-4AK60 without derating the load.

Where can I buy 3RT2026-4AK60?

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

What compliance documentation does Siemens provide for 3RT2026-4AK60?

RoHS, REACH, UL, and IEC documentation is available from Siemens on request.
