Product Positioning

The 3RT2027-1AC24 is also part of the Siemens SIRIUS S0 housing series. Its AC-3 main circuit is rated at 32A, corresponding to 15kW at 400V. Unlike the standard model, it features four auxiliary contacts (2NO + 2NC), making it suitable for motor control circuits requiring multiple interlocking or monitoring feedback points, such as those simultaneously transmitting operating status and drive indicator lights. Kenxin Motors provides authorized Siemens parts and can assist with selection based on actual panel wiring requirements.

Core Product Advantages and Features
Four sets of auxiliary contact configuration
The 2NO+2NC design is implemented in one step, reducing the need for additional auxiliary contact modules and simplifying control panel wiring and reducing costs.
24V AC standard coil
The coil operating range is 0.8~1.1 times the rated voltage (50Hz) and 0.85~1.1 times (60Hz), compatible with general PLC/24V control circuits.
S0 chassis compatible design
It shares mounting dimensions and accessories with the 3RT2027 components in the same series, facilitating standardized panel design.
Long service life
With a mechanical life of approximately 10 million cycles and an electrical life of approximately 5 million cycles (including auxiliary contact blocks), it is suitable for applications requiring frequent opening and closing.
