Three-phase switchgear PCS-9830

circuit breakermodular

The PCS-9830 switching controller is a three-phase control device for circuit breakers it serves to open or close at specified phase angle on voltage waveform in order to minimize the impulse caused by switching on. The controlled switching technology significantly eliminates harmful electrical transients upon planned switching, and thereby extending the breakers life time and improving the stability of the entire power system.
