To avoid this, fuses or circuit breakers can be installed at both ends of the varistor or power supply; The fuses of the following specifications are for reference only: Diameter 05D 07D 10D 14D 20D Rated current of fuse 1-2A 2-3A 3-5A 3-10A 5-15A 2) Do not allow the current and energy flowing into the varistor to exceed its rated value. 3) The marked VDR product brand names and marks are all patent applications of the company. Customers who use or sell VDR products that are not specifically designated for such applications are at their own risk. 4) All VDR products, product specifications and data are subject to change without notice, please improve. For any data sheet Or any other data sheet. Any errors included. Inaccurate or incomplete shall not be liable. 5) Regarding the suitability of products for specific applications. It is the customer's responsibility to confirm that products with the characteristics described in the product specifications application. The data provided in the parameter data sheets and / or specifications may vary for different applications and performance may vary over time Variety. All operating parameters, including typical parameters, must be provided by the cus.
