Product Notes

“Hi-Temp” Cartridge Specifications:

Wattage Tolerances
+5% -10% based on Nema Standards

Resistance Tolerances
+10% -5% to give above average tolerances. Note that the above tolerances are based on internal operating temperatures since the room temperature resistance of an element wire is normally 5% lower than operating.

Diameter Tolerances (inches)
¼" = .247" (+/- .002")
5/16" = .310" (+/- .002")
3/8" = .370" (+/- .002")
½" = .495" (+/- .002")
5/8" = .620" (+/- .002")
¾ = .745" (+/- .002")
*Diameter at each end may vary, +.002" to -.004"

Centreless Grinding Tolerance
(all standard diameters) ±.0005"

Length Tolerances
±2%, with ±1/8" (3mm) min. tolerance, whichever is greater.
For closer tolerances contact factory.

Camber tolerances
.020" per foot of length.

Recommended Maximum Voltages (inches)
¼", 5/16", 3/8", ½" - 240 Volts
5/8", ¾" - 480 Volts

Maximum Amperages (inches)
¼" - 3.2 Amps
5/16" – 5.8 Amps
3/8" – 7.5 Amps
½" - 12.5 Amps
