Power factor correction contactor

The range of capacitor contactors of the EPCOS B44066S*J230/N230 series has been extended by a 100-kvar version for PFC equipment with and without reactors, which increases the range to a total of seven power stages: 12.5, 20, 25, 33, 50, 75 and 100 kVAr.

This product enables a 100-kvar circuit to be implemented with only one contactor, obviating the need to connect two 50-kvar components as before. This allows better utilisation of the space in the switching cabinet.

The contactor offers the same benefits as the other models within the series, including avoidance of transients, longer operating life of the capacitor and the whole PFC system through optimised switching behaviour, reduced resistive losses and significant attenuation of high in-rush currents.

The pre-charging resistors for attenuating the transients are integrated into the package in the new type, unlike in the lower-power versions. Two variants are available: B44066S9910J230 and B44066S9910N230, the latter designed exclusively for applications with reactors.
