Features of the BF1
For one or three phase systems
Frequency supervision (hysteresis 0.5% fn)
Self-powered – No aux. Voltage needed
Operational from −25°C to 70°C
The relay BF1 of the BASIC LINE is equipped with an independent over- (f>) and underfrequency supervision (f<) with separate adjustable pickup values and trip delays. The measured frequency is continuously com-pared with the set reference values.
The BF1 is designed to be fastened onto a DIN-rail acc. to DIN EN 50022. (This is the case for all relays of the BASIC LINE.)
