Professional resistors with adjustment collar with excellent electrical and mechanical characteristics, indicated for use where high power, safe operation and durability is required.

The external coating is protected by a layer of vitreous enamel.

The resistive element consists of wire in Ni-Cr alloy or constantan, twisted on an extremely pure cylindrical ceramic plate.

They can be produced with different terminations depending on the model and ohm value, standard flag type B, with fast-on and pattern terminals, and in versions with 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.
