Product Positioning

The 3RT2027-1AD00 is a Siemens SIRIUS 3RT2 series S0 housing contactor. Its main circuit AC-3 rated current is 32A, suitable for a 15kW motor load at 400V. It is a common small-to-medium power motor starting and stopping element in Taiwanese electromechanical control panels. This model features a 42V AC 50/60Hz operating coil, suitable for some European-style or special control voltage requirements panel designs. It also has built-in 1NO+1NC auxiliary contacts for convenient signal feedback wiring. Kenxin Motor is an authorized Siemens distributor, providing genuine products and technical consultation.

Core Product Advantages and Features
S0 compact chassis design
With a width of only 45mm and a depth of 97mm, it features DIN rail mounting, effectively saving control panel space and facilitating side-by-side configuration with other components in the 3RT2027 series.
42V AC operating coil
The coil operating range is 0.8~1.1 times the rated voltage (50Hz) and 0.85~1.1 times (60Hz), suitable for electromechanical systems with special low voltage control circuits.
1NO+1NC auxiliary contact
It comes standard with one set of normally open and one set of normally closed auxiliary contacts, which facilitates interlocking and feedback of operating status.
High mechanical life design
With a mechanical life of 10 million operations, it is designed in accordance with the IEC 60947-4-1 standard, ensuring stable and reliable long-term operation.
