Description
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%)
- Adjustable time delay from 0.1s to 10s
- SPDT 10A 250VAC(Resistive load) switch
The relay operates if any of the conditions occurs.
The relay releases if any of the conditions fails.
There is a Time Delay between the relay action and the condition occurs (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%).
