CONTRUCTION 1.Seamless stainless steel sheath
2. Post terminals
3. Ceramic element support
4. Element wire situated close to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric qualities
5. Magnesium oxide packing
6. Aluminum fins offering maximum radiating surface and providing for rapid heat transfer to the surrounding medium. Stainless steel fins are available for corrosive environments. Aluminum fins are standard.
TOLERANCESLength: Up to 610 mm (24"), ±1.6 mm (1/16"); 610 mm (24") and over, ±3.2 mm (1/8") Wattage: -10 to 5% at rated voltage
