SEG BF1-230 BF 1-230 BF1 230 BF 1 230 FREQUENCY RELAY - GENUINE ORIGINAL
Brand = SEG Part Number = BF 1 - 230 Description = Frequency Relay Technical Data rated voltage Un = 110 V, 230 V, 400 V AC frequency range at 50 Hz rated frequency: 46 - 54 Hz 60 Hz rated frequency: 55,2 - 64,8 Hz hysteresis: 0,5% of nominal frequency power consumption: 3,7 VA thermal load carrying capacity: continuously 1,3 x Un returning time: 250 ms minimum operating time: 250 ms Output relays: max. breaking capacity ohmic: 250 V AC/120 W DC inductive: 500 V AC/75 W DC rated current: 5 A making current: 20 A System data: regulations: VDE 0435 part 303 temperature range at storage and operation: - 25C bis + 70C Mechanical stress: shock: class 1 acc. to DIN IEC 255-21-2 vibration: class 1 acc. to DIN IEC 255-21-1 degree of protection: IP 40 at closed front cover weight: approx. 0,5 kg mounting position: any 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.) Settings Parameter = Range f< = 92 … 100% fn tf< = 0 … 10 s f> = 100 … 108% fn tf> = 0 … 10 s Order Variants of the BF1 BF1-110 — Rated voltage 110 V AC BF1-230 — Rated voltage 230 V AC BF1-400 — Rated voltage 400 V AC
