ABB CM-PFE

ABB CM-PFE is a relay for monitoring the phase sequence of a three-phase power supply. It can detect whether the power supply phase sequence is correct and provide the corresponding output signal to protect the connected device. CM-PFE is often used for the protection of motors, frequency converters and other equipment to prevent equipment damage due to phase sequence errors.

Main function

Phase sequence detection: Detect whether the phase sequence of the three-phase power supply is correct (positive or reverse sequence).
Phase loss protection: Detects whether the three-phase power supply has phase loss.
Overvoltage/undervoltage protection: Some models also have overvoltage and undervoltage protection.
Output signal: Provides contact output that can be connected to other control device

s or alarm systems.
