RTR Energía’s thyristor-based static contactors are designed for automatically controlled reactive energy compensation and where an immediate connection response is required.
These contactors can connect capacitive loads up to 80kVAr in less than 10ms after receiving the trip signal. Its design is based on a powerful microprocessor with algorithms that allow switching at the moment the voltage passes through zero, avoiding deterioration of the capacitor.
