Product Positioning

The 3RT2026-1AD00 belongs to the Siemens SIRIUS 3RT20 series S00 miniature contactor family. Its main circuit can handle a current capacity of AC-3 11kW/400V, 25A. It features 1 NO + 1 NC auxiliary contacts. The 42V AC coil specification is commonly used in applications where existing panels still use a 42V control power supply, eliminating the need for replacing the control transformer. Kenxin Motor is an authorized Siemens distributor, providing genuine products with warranty and comprehensive selection consultation.

Core Product Advantages and Features
42V AC coil compatible with existing wiring
For older panel designs that still use 42V control power, the original specifications can be replaced without modifying the control transformer, reducing the time and cost of panel modification.
AC-3 11kW/400V main circuit capacity
The 25A rated current can directly correspond to three-phase motors of 7.5~11kW, covering the start-stop control needs of general pumps, fans and conveyors.
Built-in 1NO+1NC auxiliary contacts
Without the need for external auxiliary contact modules, it can provide status feedback or interlock signals to the control panel PLC and indicator light circuits.
S00 small frame, screw terminals
Its compact size facilitates the layout of high-density distribution boxes, and the screw terminal installation method is consistent with the common construction method used by Taiwanese electrical panel installers.
