Rectangular duct heater 400×300×300 mm with finned tubular elements, 4 kW 400 V three-phase, with contactor and thermostat - RE-TCC-SCTTC

Electric duct heater for rectangular ventilation ducts, with a 400×300×300 mm duct section: 4 kW at 400 V three-phase.

The rectangular duct section fits straight into the ductwork, and the heater works as an electric heater battery for air heating in HVAC and ventilation systems.

The heating elements are tubular (sheathed) elements: the resistance wire is enclosed in a protective metal sheath.

The RE-TCC-SCTTC version includes a contactor and a bulb and capillary thermostat adjustable from -30 °C to +30 °C, mounted on the air inlet: set the switching temperature and the heater switches on by itself when it is reached.

Two thermal cut-outs, one with automatic reset and one with manual reset, trip if the airflow is missing or insufficient; the terminal block and cable glands are factory-fitted.
