Product Positioning

The 3RT2025-1AN24 also uses a 220V control voltage, but has a 2NO+2NC configuration with more auxiliary contacts. Compared with the standard 1NO+1NC model, it has one more set of contacts for interlocking, indicator lights or PLC signal feedback, making it suitable for control box designs with more complex circuits that require multiple interlocks or monitoring signals.

Core Product Advantages and Features
Double auxiliary contacts are more flexible
2NO+2NC can simultaneously provide start indication, interlocking loop and status feedback, reducing the cost of adding external auxiliary contact modules.
The 220V control voltage will continue to use the existing wiring.
It is compatible with common AC220V control circuits in Taiwan, and the original wiring and terminal blocks can be directly reused when replacing the unit.
S0 compact frame, highly flexible installation
It has the same dimensions as the 1NO+1NC model in the same series, making it easy to directly replace and upgrade existing distribution box designs.
Siemens authorized suppliers, specifications are traceable
Kenxin Motors provides complete original part numbers and batch numbers for easy future maintenance and specification comparison.
