The Siemens 3RT7026-1AH05 is a SIRIUS S0-size contactor with three main NO contacts and an AC control coil.
Side-by-side mounting is permitted, so panel fill factor is straightforward — the 55 mm width per unit is the only horizontal space needed.
For AC-3 duty (motor switching), the maximum operating voltage is 690 V, and the contactor can handle up to 800 switching operations per hour at AC-3, or 250 per hour at AC-4 (plugging/inching).
This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.
Both are S0-size contactors with screw-type terminals and similar DIN-rail mounting, so the mechanical footprint and terminal layout are compatible. The 3RT7026-1AH05 uses an AC control coil, while the 3RT6028-1AB00 may differ in coil voltage — verify the control supply matches before substitution.
Standard Siemens declarations include RoHS, REACH, and IEC compliance documentation, provided with the shipment.
