sequence and phase failure in three-phase mains.
Characteristics
–– Monitoring of three-phase mains for phase sequence and
phase failure
–– Powered by the measuring circuit
–– 1 c/o (SPDT) contact
–– 22.5 mm (0.89 in) width
–– 1 LED for the indication of operational states

Application / Operating mode
The CM-PFE is designed for use in three-phase mains for monitoring the phase parameters phase sequence and phase
failure.
The CM-PFE works according to the closed-circuit principle.

Phase sequence and phase failure monitoring
If all phases are present with the correct phase sequence, the output relay energizes after the fixed start-up delay ts is
complete.
If a phase failure or a phase sequence error occurs, the fixed tripping delay tv starts. When timing is complete, the output
relay de-energizes. The LED R glows when the output relay is energized.
In case of motors which continue running with only two phases, the CM-PFE detects phase failure if the reverse fed voltage
is less than 60 % of the originally applied voltage.
