Product Description
Specifications
1.three phase unbalance protection2.Under voltage,over voltage and Phase failure protection
3.Time delay from 0.1s to 10s
3 phase supply control relay
(Phase sequence relay) 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 0.1s to 10s.
When the supply returns towards its rated value, the relay is re-energised according to the hysteresis value (5%).
