Description

The Fasealert F3P is a very reliable phase fault relay with state-of-the-art technology that protects motors and three-phase equipment of any capacity and for all types of starters against low voltage, high voltage, phase failure, voltage imbalance, and reverse sequence.

The F3P protects by disconnecting the contactor coil and turning off the motor or equipment when it detects any voltage faults. It has an internal contact that opens or closes according to the voltage conditions.

It has indicator LEDs for normal voltages and each fault.

This equipment allows adjusting the protection levels for high and low voltages, as well as the disconnection delay to avoid disconnection due to a transient fault. Similarly, it has an adjustable connection delay that waits for a certain time before reconnecting when the voltages are normal.

Optional equipment

Adapter plate for DIN rail mounting
