Line reactor SA, SB, SC series

aircurrentsingle-phase

SA, SB and SC series damping reactor coil. These non-iron (air core) damping reactor coils are used to absorb transients and inrush currents. In series with the capacitor, the reactor coil reduces the inrush surge in the capacitor at a value that does not fatigue the insulation or damage the internal connections of the capacitor’s parts. Such a reactor coil remains connected following capacitor excitation. As a result, it must be designed around the continuous load current to which the capacitor is exposed. Unless otherwise indicated, reactor coils are designed for a current overload of 43% and a failure level 25 times the rated current.
