Touch-Safe PTC Heater
CSK 060| 10 & 20 W

  • Low surface temperature
  • Compact size
  • Wide voltage range
  • Double insulated protection
  • DIN rail mountable

The CSK 060 is a touch-safe heater for use in enclosures. The design of the heater utilizes natural convection which results in a circulating current of warm air. The surface temperatures on the accessible side surfaces of the housing are minimized as a result of the heater design. This heater is suitable for permanent operation.
