Siemens 3RT2026-1AK60 Three Phase Industrial Contactor

This Siemens Sirius 3RT2026-1AK60 three-pole power contactor is built for robust AC-3 motor control in control panels and industrial equipment. It features a 3PST-NO main contact arrangement with a single 1 NO + 1 NC auxiliary contact, all housed in a DIN-rail–mountable chassis (size S0) for compact cabinet layouts. The coil operates on 120 V AC (60 Hz), allowing direct control from standard control circuits, while the main contacts are rated for AC-3e/AC-3 loads up to 25 A, with a common practical capacity of about 11 kW at 400 V. The device carries an insulation voltage of 690 V, and termination is via screw terminals for secure, reliable wiring. Designed for demanding environments, it supports long mechanical life (millions of operating cycles) and substantial electrical life under load, making it suitable for motor starters in conveyors, pumps, fans, and HVAC systems, as well as other three-phase switching applications. As part of Siemens' SIRIUS 3RT2 family, the 3RT2026-1AK60 offers a proven combination of rugged performance, ease of integration, and straightforward wiring in compact industrial controls.
