Alco start-up current limiter CSS-32U VDE 805204

The Soft Starter in the CSS series is used for limiting the starting current for 1-phase compressors. The integrated starting capacitor increases the moment of torque when the compressor starts and is then shut off. The compressor is constantly monitored during operation and shuts off if the voltage is too low. It is restarted only after a time delay. The green LED flashes during the delay period. If there is a fault, then the red LED will light up; the alarm relay is also activated.

• For single-phase motors with max. rated current of 25 A/32 A
• Starting current limited to under 45 A
• Automatically adapts for mains frequencies of 50 Hz and 60 Hz
• Automatically adapted to the motor current - no manual settings required
• Alarm relay output
• The integrated starting capacitor improves the initial moment of torque and is shut off once the motor is running
• Motor protection function:
  • Shuts off if voltage is too low
  • Detects a blocked rotor and shuts off
  • Delay function to limit the number times the motor is started per hour
• Thyristor protection for a long contact service life
• No additional motor contactor required
• Self-test
• Multifunctional clip for installing on cap rails - choice of two directions
• Cage clamps for easy electrical connection
