Single Phase: Band heaters are usually designed on 230 Volts single phase unless specified.
Dual Phase: Ceramic Band Heaters can be designed with multiple circuits to operate in single or three-phase circuits.
Three Phase: On very high wattage band heaters it would be advantageous to install three-phase wiring to reduce the current load across a single conductor. Three-Phase wiring is available with all types of insulation, Construction styles, and clamping variations.
Limitations: Minimum width: 3"(76.2mm).
