FP31-serien 3-phase monitoring relays i is a phase -sequence/phase – asymmetry relay with fixed reaction delay and adjustable setpoint.
Compared with FP30 the relay does not release, if all 3 voltages are higher or lower than the nominal voltages, as long as the asymmetry between them is lower than the setpoint.
The standard type has a delay – ON and delay – OFF time at 1 sec., and an adjustabe setpoint from 5 to 25 %
Modulet kan desuden leveres kun med ind- eller udkoblingsforbindelse,
samt med andre tidsforsinkelser eller setpunktområde
Option ally, the unit can be delivered with ON – delay or OFF – delay only, with different delay times, or with different setpoint range
