OnLoad changeover switch from 63 to 3150 A

Manually operated sheet steel enclosed changeover switches provide changeover, source inversion or switching under load between two low voltage power circuits, as well as their safety isolation. The enclosure provides protection against contact with live parts as well as environmental factors such as dust, water and other hazards.

  • On load manual changeover between 2 sources
  • Emergency breaking
  • Selection between two loads
  • Safe isolation of downstream loads for maintenance purpose
