Type 3PH: Three Phase

In order to minimize the gauge of the wiring on high wattage cartridge heaters, 3-phase elements can be designed.

Type DV: Dual Voltage

3/8″ and 1/2″ diameter heaters may require a larger diameter transition area at the lead end. Cartridge heaters can be designed using 3-wire series/parallel circuits for dual voltage applications. Whether the heater is run on a high or low voltage, the wattage will be the same. DV1 120/240 volts DV2 240/480 volts

Type GJ: Grounded Element Winding

For DC applications where the electrical circuit is negative grounded, the cartridge heater can be designed with one side of the element winding grounded to the sheath and a single lead wire exiting the cartridge heater.

Type GL: Ground Lead/Sheath

For those applications requiring a separate ground lead attached to the cartridge heater sheath. Standard ground lead wire is a 10″ long insulated stranded conductor. Optional insulated and color-coded leads are available.
