The PFC2 range of Capacitor switches provide optimised switching and control of three phase capacitive loads for Power Factor Correction, suitable for a three phase supply using the two-leg control technique. Signal control is by a DC signal. They incorporate an automatic resetting temperature trip fitted to the heatsink. They also have an integral semiconductor power fuses. The four models in this series include the 30kVAR, 50kVAR, 80kVAR and the 100kVAR models, all of which are fan cooled.
