Product Overview: The KE-FKR4 is designed for precision motor protection. Unlike standard relays, this model allows the user to adjust upper and lower voltage limits, asymmetry threshold, and trip delay. This feature prevents unnecessary motor shutdowns in areas with frequent grid fluctuations (thanks to the delay) while ensuring total safety.

Summary of Advantages

• Adjustable Sensitivity: Custom protection thresholds tailored to the specific needs of every motor.

• Trip Delay: Prevents "nuisance tripping" caused by momentary grid noise or fluctuations.

• Flexible Mounting: Compatible with standard DIN rails, available in an economical 8-unit pack.
