Abstract

The invention discloses a three-phase fuse, comprising three single-phase type fuses which are installed on an insulating mounting base side by side; an insulating separator is arranged between two adjacent single-phase type fuses. The invention has the advantages of compact structure, little occupied space and simplified operation.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and in particular relates to a three-phase fuse. Background technique [0002] Traditional fuses are mostly single-phase. When used in three-phase circuits, a single-phase fuse is generally used in each phase circuit for overcurrent protection in the three-phase circuit. As we all know, the use of three separate fuses to meet the use of three-phase circuits is cumbersome and inconvenient to operate, and its structure needs to be improved urgently. Contents of the invention [0003] The object of the present invention is to provide a three-phase fuse with compact structure, small space occupation and relatively simplified operation. [0004] The technical solution to achieve the purpose of the present invention is: a three-phase fuse, including three single-phase fuses, the three single-phase fuses are installed side by side on an insulating mounting base, and two adja...
