15Pcs 380V 4A Fast Blow Fuse, Ceramic Cartridge Fuses Microwave Fuse

What is this?These 10x38mm F-type ceramic fuses offer fast-acting protection for 380V industrial equipment, power systems, and machinery. Featuring rapid overload response, time delay fuse ensure reliable safety in critical circuit applications.What will I get?Color: Silver White;Material: Ceramic;Fuse Size: 10 x 38mm / 0.39 x 1.5 Inch (Diameter*Length);Rated Voltage: 380V;Rated Current: 4A;Breaking Speed: F (Fast-acting);Package Contents: 15Pcs x Ceramic FusesIs there any advantages of the product?The ceramic construction provides better heat resistance and arc suppression compared to glass fuses, while the compact 10x38mm size fits standard fuse holders. These fuses feature precise current ratings for reliable overflow protection and maintain stable performance under 380V working conditions. The fast-acting F-type design offers quicker response to short circuits than slow-blow alternatives, helping protect sensitive equipment.How to use it?Install the fuse in compatible 10x38mm fuse holders with matching voltage and current ratings. Ensure proper orientation and secure contact with the fuse clips. The fuse automatically stop the circuit when current exceeds the 1A rating, at which point replacement is required. Always verify system voltage matches the fuse's 380V rating before installation.What should I notice?Use only in dry environments and avoid exposure to moisture. Never replace with higher-rated fuses as this may cause equipment damage. These are one-time-use fuses that require replacement after operation. For optimal performance, ensure proper fuse holder contact pressure and clean connection surfaces.
