Features When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, which corresponds to a resistance with infinite value. Equivalent to a switch off Adopted by high-quality electronic components and accuracy process, ensure durability When the voltage applied to the varistor exceeds its threshold, the current flowing through it increases, which corresponds to an infinitely small resistance corresponding to a closed state switch. The varistor has good contact performance, ensures stable working Small body, easy to install and remove. Specification: Condition: 100% Brand New Item Type: Varistor Diameter: Approx. 10mm/0.4" Voltage: 430V Package Size: Approx. 10 x 10 x 2 cm / 3.9 x 3.9 x 0.8 inches. Features: 1. The varistor has good contact performance, ensures stable work. 2. Small body, easy to install and remove. 3. When the voltage applied to the varistor exceeds its threshold, the current flowing through it increases, which corresponds to an infinitely small resistance corresponding to a switch when closed. 4. Adopted by high-quality electronic components and accuracy process, ensure durability. 5. When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, which corresponds to a resistance with infinite value. Equivalent to a switch off Package list: 50 x varistors Package List
