Loop Heater LP 165


LP 165 | 60 W to 150 W
Compact heater with PTC heating elements for heating enclosures with electrical or electronic components. The innovative aluminium profile in loop design creates a chimney effect, which ensures great convection resulting in excellent heat dissipation within the enclosure. The practical push-in clamping terminal ensures quick and easy electrical connection.
  • Clip fixing and pressure clamp for quick mounting
  • Dynamic heating up through PTC technology
  • Heater body in loop design for optimal temperature distribution
  • Wide voltage range
  • Additional approvals
