Phase loss and phase
sequence sensor
Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.
Purpose
The CKF-319 phase loss and phase sequence microprocessor
sensor without neutral wire is designed to protect electric motor
powered from the three-phase network in following cases:
» voltage loss in at least one phase;
» voltage drop in at least one phase below 150 V;
» voltage increase in at least one phase above 280 V;
» voltage asymmetry between phases above the set value;
» incorrect phase sequence.
The sensor correctly measures the true rms value of the
voltage (TrueRMS), even when the power supply voltage
is (disturbed) distorted.
