Product Description

This is designed to monitor 3-phase supplies and to protect
motors and other loads against the faults listed below.
 Monitoring of rotational direction of phases
 Detection of complete failure of one or more of the phases
 Undervoltage detection (-10%)
 Overvoltage detection (+10%)
 Detection of phase asymmetry (imbalance) (±10%)
The relay operates if any of the conditions occours.
The relay releases if any of the conditions fails.
There is a Time Delay between the relay action and the condition occours (except rotational direction of phases error)
to avoid very short interruptions or other momentary failures.
A selector switch allows selection of an adjustable time delay from 0.1 s to 10 s.
When the supply returns towards its rated value, the relay is re-energised according to the hysteresis value (5%)
