Tubular heater offers three-phase capability.

Packaging a thermocouple inside a heater with one or more resistance coils allowsWatlow Electric Manufacturing Co.to offer a tubular heater with three-phase capability. This capability means that only one element is required, thereby lowering amperage and reducing installation time and cost. The multicore three-phase heater can be single-ended with three leads for three-phase wye hookup.
