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.
