LR3 40-4/10 Block United Kingdom Sales
The BLOCK LR3 40-4/10 is a three-phase line reactor designed to ensure a short-circuit voltage of 3–5% to the mains, providing power harmonic damping and starting current limitation. With an inductance of 3 × 5.9 mH and a rated current of 3 × 10 A AC, it operates within a voltage range of 0 V to 690 V and is rated at 400 V. The reactor features integrated lifting rings and multifunctional fixing rails, offering flexibility in installation. Its vacuum impregnation process ensures very good corrosion protection and low noise operation.
