The NCH-11000 Series range of natural convection heaters consists of a ceramic type heating element, with electrically insulated and corrosion resistant (anodized) heat-sink fins. A UL94V-0 heater guard in high temperature plastic is provided to protect from accidental contact with the element. Elements are self-regulating giving the highest power at a low ambient temperature. There are four primary variants giving different powers. Additionally heaters are built as low and high temperature versions. Heaters NCH-11000 and NCH-11100 are low temperature versions the plastic heater guard does not exceed 74°C (165°F). Heaters NCH-11200 and NCH-11300 are hotter allowing higher power output however the plastic heater guard does not exceed a safe 105°C (221°F). The heating element conforms to IP20. For ease of installation the product is supplied with a factory fitted stainless steel 35 mm DIN-rail mounting clip. Electrical connection is via a terminal block which is integrated with the heater guard. All elements are optimized for low inrush current across the permissible voltage range.
