SEG BU1-AC-400 VOLTAGE RELAY SEG BU1AC400 BU1 AC 400 - GENUINE ORIGINAL

Brand = SEG

Part Number = BU1-AC-400

Description = Voltage Relay

Application

Under- and over-frequency supervision of single or three-phase systems.

Function

The unit BF1 is equipped with an independent over (f>) and under-frequency supervision (f<) with separate adjustable pickup values and trip delays.

The measured frequency is continuously compared with the set reference values.

For frequency supervision the cycle duration is evaluated and so measuring is virtually independent on harmonics.

To avoid tripping during normal operation due to interference voltages, a fixed measuring repetition is used.
