A compact and cost-effective soft starter

An extremely cost-effective and compact soft starter that provides basic soft start and stop functionality and easy DIN rail mounting.

The ‘fit and forget’ semiconductor design simplifies installation and reduces required panel space, and selection can be made on the basis of the motor power. Timed voltage ramp up and down are possible. Ramp time can be individually and accurately adjusted with rotary switches from 0.4–10 seconds, and starting torque can be adjusted from 0–85% of the direct on-line torque.

Supply voltages and power range 

  • 3 x 208-600 V...0.1-11 kW (25 A)
  • 24-480 V AC or DC

Features and benefits

Panel space can be saved due to the compact size

Selection is simple and stock is kept to a minimum thanks to universal control voltage

Commissioning time and space are saved as a result of easy DIN rail mounting for sizes up to 30 kW

Reliable operation is ensured due to robust semiconductor design and an almost unlimited number of starts per hour without derating

No external cooling or oversizing is necessary thanks to the maximum ambient temperature of 50°C without derating
