Thyristor switching module is for high speed Reactive Power Compensation Systems in Low Voltage grids from 415 / 440 V, 50 Hz, using single or multiple components of 50kVAr, 25kVAr & 10kVAr. Suitable for capacitor units with or without detuning reactor.

• Electronic Switching Voltage 415v/440v/690V/750V +- 10%
• Fast discharge reactor
• Temperature Controlled, forced air cooling for all models
• Builts in alarms for protection of switching module & capacitor banks
• High Peak Inverse Voltage (PIV) – 2.2 kV
• l Lower operating losses
• l Auto thermal cut off
• Thyristor Switches for Dynamic Power Factor Correction
  System with Harmonic Block Reactors.
