company news about Classification of low-voltage pipe-mounted fuses

        Fuse is a kind of short circuit protector, which is widely used in power distribution system, control system and new energy charging pile, mainly for short circuit protection or serious overload protection. Fuses are widely used in low-voltage systems because of their simple structure, convenient use and low price.

        Now let's introduce the classification of low-voltage cartridge fuses according to their applications：

1. For residence and similar occasions, type gG;

2. For industrial applications, type gG, gM or aM.

        The first letter indicates the blowout range: "g" indicates that it is a fuse with a full range of fusing capacity; "a" indicates that it is a fuse with a partial range of fusing capacity.

        The second letter indicates the application category, and this letter specifies the time-current characteristic, conventional time and current.

Example:

"gG" denotes a general-purpose full-range fuse;

"gM" denotes a fuse with full range of fusing capacity for protection of motor circuits;

"aM" denotes a fuse with a partial range of fusing capacity used to protect the motor circuit.
