Shielded electric resistance heaters are fully factory-wired
and tested. Each stage is protected against overloads by two
thermal protectors. The low-limit protector with
automatic reset is located above the resistance heaters while
the high-limit protector with manual reset is located in the
heater control box. This high-temperature limit control
offers overload protection and is set to 90°C. It is located
