Product Positioning

The 3RT2025-1AK60 features a 110/120V dual-frequency coil design, allowing the same coil to automatically adapt to both 50Hz (110V) and 60Hz (120V) AC mains power specifications. This makes it particularly suitable for OEM equipment manufacturers exporting to North America or those needing to accommodate both Taiwanese and US power systems. 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: one coil serves two purposes
The 110V/50Hz and 120V/60Hz models share the same coil design, so export-oriented machines do not need to prepare materials separately according to different mains power specifications.
Suitable for export to North American specifications
It corresponds to the US standard 120V/60Hz control voltage and is a coil specification commonly used by Taiwanese machine tool manufacturers for export to the North American market.
S0 frame, unchanged volume
The dual-frequency coil model has the same appearance as the standard model, and the panel configuration diagram can be used directly.
