Protected Resistor 6X60X450 SAC/PR – 9000W

Cemented tubular wirewound resistor composed by a ceramic tube with a high heat dissipation level and mechanical resistance used as support for the resistive wire or ribbon. Covering the tube and the extremities, we use a galvanised steel enclosure suitably perforated for correct ventilation. This protection is IP20. We can supply it with or without thermal sensor and with the customer’s ohm value specification.
