Product Positioning

The 3RT2026-1AD20 is a SIRIUS 3RT2 series S00 frame three-pole contactor. The AC-3 version is rated at 25A and 11kW at 400V, while the AC-1 version is rated up to 40A. According to the manufacturer's universal selection chart, the control coil is a 48V AC, 50/60Hz dual-frequency design, belonging to the lower voltage range coil option in the series. It has 1 NO + 1 NC auxiliary contacts and is suitable for applications where the existing control circuit already uses a 48V configuration, or where a lower coil circuit voltage level is desired to improve operator safety margins.

Core Product Advantages and Features
48V AC 50/60Hz low voltage coil
The control voltage level is lower than that of a typical 110/220V coil, and the dual-frequency design can be used in 50Hz or 60Hz power supply environments.
1NO+1NC Built-in Auxiliary Contacts
A set of normally open and normally closed signals can be obtained without the need for external modules, which can be used for feedback or interlock control.
AC-1 rated 40A
The rated current for resistive loads can reach 40A, providing greater selection flexibility than simply calculating based on AC-3.
S00 standard framework compatibility
It shares the same shape and mounting hole positions as other coil voltage models in the series, which facilitates unified spare parts planning.
