By using a mains choke the upper harmonics are reduced and the starting current is limited. This increases the efficiency and discharges the leads.

• Easy installation
• Small footprint
• Reduction of cable looms in control panels
• Attenuation of higher harmonics
• Low hum vacuum impregnated choke
  Reduced start-up current
• The choke is rated for a short-circuit voltage of 4%, at rated current, as standard
