Ferrule Semiconductor Protection Fuses, 10x38 to 20x127 mm

DENCO ferrule semiconductor protection fuses are cartridge (midget) fuses for protecting power semiconductors. The catalog lists 2A to 200A in six sizes from 10x38 mm to 20x127 mm, with voltage pairs of 220V/500V, 220V/600V, 220V/660V and 220V/750V, and indicator options. They are made in accordance with IEC 269.1 and VDE 636-23.
