DIN Rail Compact PTC Fan Heater NTL 401 • 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 clamb connectors save time and simplify installation.
