ABB EF45-30 Electronic Overload Relay | 9.0A to 30.0A Range

1SAX221001R1101
ABB EF45-30 is a state-of-the-art electronic overload relay engineered to protect motors from 9.0 to 30.0 Amps. Specifically optimized for use with AF26, AF30, and AF38 contactors, it offers a wider setting range and higher accuracy than traditional bimetallic relays. With its ability to handle different trip classes, it is the ideal choice for protecting pumps, fans, and conveyors in demanding industrial environments.

Key Technical Features:

Extended Setting Range: The 9.0–30.0A range allows for versatile application across various motor sizes with a single device.

Selectable Trip Classes: Features adjustable trip classes (10E, 20E, 30E), providing tailored protection for both standard and heavy-duty motor starts.

Advanced Phase Loss Protection: Electronics-based sensing ensures rapid tripping in the event of phase failure or imbalance, preventing motor burnout.

Temperature Compensated: Maintaining its trip curve regardless of ambient temperature changes, ensuring reliable protection in hot control rooms.

Low Energy Consumption: Reduces internal heat generation by up to 50% compared to thermal relays, increasing the lifespan of your control cabinet components.
