”B” Ring
The ceramic tubular core ensures high dissipation capacity and excellent resistance to thermal shock and overload. The resistor
winding is evenly coiled on the core and protected by an enamel coating. A longitudinal opening provides for one or more
electrical connections by means of sliding collars equipped with a tongued connector.
