Note: * Insert “High-Limit Thermostat Temperature” rating from above table. The maximum allowable sheath temperature (“T” rating) must be specified if drum heater is to be used in a Division II area. “C” specifies heaters with adjustable temperature control assembly and temperature ranges from -4 to 163°C (25 to 325°F).
** Article 501 of the NEC requires that the maximum sheath temperature of the heater shall not exceed 80 percent of the auto-ignition temperature of the surrounding atmosphere when heater is continuously energized.
Auto-Ignition Temperature: The minimum temperature required to initiate or cause selfsustained combustion of a solid, liquid or gas independently of the heating or heated element (see NFPA 325M, Fire Hazard Properties of Flammable Liquids, Gases, and Volatile Solids).
