Industrial resistors with excellent electrical and mechanical characteristics, indicated for use where high power, safe operation and durability is required.
The external coating is protected by total coverage in vitreous enamel.
The resistive element consists of wire in Ni-Cr alloy or constantan, twisted on an extremely pure cylindrical ceramic support
They can be produced with different terminations depending on the model and ohm value, standard flag type B, with fast-on and pattern terminals, in a version with intermediate collars (divider) and off-standard tolerances
The adjustment collar enables an intermediate value to be established. The stability of the contact is guaranteed up to the maximum surface temperature of 350°C.
N.B.: For adjustable resistors, you must keep in mind that the nominal power is understood as applied to the entire resistor, if only part of it is powered, the power applied must be reduced in proportion to the part that is not used.
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 dissipating nominal power from the resistor increases based on the speed of the air.
