Switchpoint Cabinet Heater HG-140


  • Pressure clamp connectors
  • Dynamic heating up
  • Wide voltage range
  • Energy saving
  • Clip fixing
  • Quick installation

These heaters are used in enclosures where damage from condensation must be prevented, or where the temperature may not fall below a minimum value. The aluminium profile heater body design has a chimney effect and distributes the heat evenly. The heaters are designed for permanent operation. Pressure clamp connectors save time and simplify installation.
