Product Positioning

The 3RT2025-1AH24 is also a 48V safety extra-low voltage coil, but it features 2NO+2NC reinforced auxiliary contacts, making it suitable for low-voltage control circuits that still require multiple interlocks or signal feedback, such as simultaneously monitoring operating status and fault reporting. The main circuit specifications are consistent with the series, rated at 17A/7.5kW (400V) AC-3.

Core Product Advantages and Features
Low-voltage coil with multiple sets of auxiliary contacts
The 48V safety extra-low voltage coil, coupled with the 2NO+2NC configuration, balances operational safety with circuit signal flexibility.
Main circuit rated maintenance series level
17A/7.5kW (400V) AC-3 rated, consistent with other voltage models and specifications without discount.
S0 framework, unified appearance
It shares the same external dimensions as other voltage models in the same series, and the panel design can be directly adopted.
Original manufacturer authorized, specifications traceable
Kenxin Motors provides complete original serial number and batch number information, and can also assist in confirming delivery dates for special specifications.
