Key Product Differences
The model number structure defines the specific configuration: NWHMTOR-<Number of Elements>-<kW Code>-<Terminal Enclosure Code>-<Voltage/Phase Code>. For example, NWHMTOR-03-005P-E1/240 denotes a unit with three elements (code 03), 5 kW power (code 005P), E1 General Purpose enclosure, and 240V single-phase supply.
Power codes correspond to specific wattage outputs: 003P for 3 kW, 04P5 for 4.5 kW, 006P for 6 kW, 07P5 for 7.5 kW, and 009P for 9 kW. The number of elements is fixed at three (code 03) across the series.
