500W Power Wire Wound Rheostat Cement Coated Ceramic Variable With Knob

● BCI series Variable Rheostat is wound with copper or chromium-alloy wire as a resistance element.Except for the slide contact surface,the entire component is coated with high-temperature,non-flammable resin.After cooling and drying,insulation is applied through a high-temperature process.Then,a centered rotating adjuster component is installed,which slide along the resistance element and varies the resistance to the desired value.
● BCI series of rheostats has been designed and manufactured to retain high reliability and smooth operation over long periods of use. These rheostats are constructed from a ceramic body with resistance alloy winding and a vitreous enamel coating (or silicone ceramic coating depending on model). BCI rheostats have a metal spring contact arm, metal graphite composition and feature solder coated terminals.
● Single unit with multiple winding resistance values is available.
● Different ceramic raw material and knobs, made-to-order rheostats available.
