Product Positioning

The 3RT2025-1AK64 also features a 110/120V dual-frequency coil design, but is equipped with 2NO+2NC reinforced auxiliary contacts, making it suitable for control box applications in North American export equipment that require multiple interlocking, indication, or safety monitoring signals. The main circuit specifications are consistent with the series, rated at 17A/7.5kW (400V) AC-3.

Core Product Advantages and Features
Dual-frequency coil with reinforced contacts
The 110V/50Hz and 120V/60Hz dual-frequency coils, along with the 2NO+2NC configuration, balance mains power compatibility and circuit signal flexibility.
Suitable for multi-chain and monitoring applications
2NO+2NC can handle interlocking, fault reporting and operation instructions simultaneously, reducing the need for additional auxiliary modules.
Common specifications for equipment exported to North America
The dual-frequency coil design allows the same batch of machines to be directly sold to regions with different mains power specifications, reducing the complexity of material preparation.
Kenxin Motors is an authorized supplier with transparent specifications.
We are an authorized Siemens distributor, providing complete original serial numbers and batch numbers for verification.
