ABB 1SAX221001R1101

The EF45-30 electronic overload relay operates without the need for an external power supply, ensuring straightforward integration into standard motor applications. This device is particularly notable for its wide setting range of 9.0 to 30 A and high accuracy, which is crucial for protecting motors effectively in various conditions.

With a rated operational voltage of 690 V AC for the main circuit and 600 V AC/DC for the auxiliary circuit, the relay accommodates multiple operational frequencies of 50 Hz and 60 Hz. The relay features trip classes selectable at 10E, 20E, and 30E, allowing customization based on specific application requirements.

Additional functionalities include temperature compensation, a trip contact (NC), a signal contact (NO), and options for both automatic and manual reset. The trip-free mechanism ensures that the relay remains operational during fault conditions while providing STOP and Test functions, along with trip indication for enhanced monitoring.

The relay is compliant with several standards including IEC/EN 60947-1 and UL 60947-1, ensuring its reliability in industrial environments. Its construction supports a temperature range of -25 to +70 °C, making it suitable for a variety of operational settings.

In terms of installation, the EF45-30 has a compact design with dimensions of 45 mm width, 104.7 mm height, and 86 mm depth, and a weight of 0.362 kg. The relay can be directly connected to contactors, and single mounting kits are available as...
