Product Description
The BC1 series of rotor-arm sliding wire porcelain disk variants are designed for voltage and current adjustment in industrial electrical equipment up to 500V. The resistor uses a round ceramic skeleton with Kanthal copper or nickel chromium wire, coated with high-temperature enamel. The sliding grip and brush mechanism provides variable resistance. The unit features a protective metal case with handwheel operation.
