Professional resistors with extremely high overload characteristics, which are mechanically very robust and non-flammable, with excellent insulation. The joints obtained with electric welding and the large size of the terminals were designed to support strong, brief overloads of short duration and are particularly suitable for use where a low resistive value and high dissipation capacity are required.
The external protection is ensured by a ceramic cement coating.
The resistive element consists of a flat wire in Ni-Cr alloy or constantan, twisted on a high quality cylindrical ceramic support.
The nominal power Pn in the table refers to the resistor placed horizontally in the open air with natural circulation with an ambient temperature of 25°C.
With forced ventilation, the nominal power dissipation capacity of the resistor increases according to the air speed.
