Product catalog summary

Technical Document Summary: Three-Phase Line Reactors

General Data:
Line reactors are designed for three-phase systems with a rated voltage of 3 x 400 Vac. They feature a short-circuit voltage range of 3-5% and a rated current range from 3 x 2 A to 3 x 1600 A. Inductance values range from 0.019 to 14.700 mH. The insulation class can be B, F, or H, and they operate in ambient temperatures from -10°C to +40°C with a protection degree of IP 00.

Advantages:
These reactors can be used as line reactors, commutating reactors, or PFC reactors. They ensure a short-circuit voltage of 3, 4, or 5% to the mains, provide power harmonic damping, limit starting current, and increase the service life of consumers. They also offer low ripple, bridge voltage dips, and limit peak current. The reactors have very good corrosion protection and low noise due to vacuum impregnation, and they feature integrated lifting rings and multifunctional fixing rails.

Applications:
Line reactors are used to minimize mains pollution, reduce reactive-power components and charging currents in the DC link capacitor, and improve the power factor (cos(phi)).

Standards and Approvals:
The reactors comply with standards such as DIN EN 61558-2-20, IEC 61558-2-20, UL 506, and CSA 22.2. They have approvals including cURus.

Operating Data:
For single-phase line reactors, the rated voltage options are 230 Vac and 400 Vac, with a voltage drop of 9.2 Vac or 16 Vac. The rated current ranges from 16 A to 25 A, with a frequency of 50-60 Hz. Inductance values vary from 1.170 mH to 3.190 mH with a deviation of ±10%. The insulation class is B, and the protection index is IP 00.

Safety and Protection:
The reactors are open type with a safety class prepared as I and a test voltage of 2500 Vac for single-phase and 4000 Vac for three-phase reactors. The type of cooling is AN (natural air cooling).
