Classification Of Fuses

- Feb 02, 2018 -

According to the form of protection, can be divided into: overcurrent protection and overheating protection. The fuse used for overcurrent protection is usually said to be a fuse (also known as a current limiting fuse). A fuse used for overheating protection is generally referred to as a "temperature fuse".

Temperature fuse is also divided into low melting point alloy shape and temperature trigger shape, as well as memory alloy shape and so on (temperature fuse is to prevent the heating of electrical appliances or heating appliances too high temperature protection,

According to the use of the range, can be divided into: Power fuses, machine tool fuses, electrical instrumentation fuse (electronic fuse), car fuses.

By volume, can be divided into: large, medium, small and micro.

According to rated voltage, can be divided into: High voltage fuse, low voltage fuse and safety voltage fuse.

According to breaking capacity, can be divided into: high, low breaking capacity fuse.

According to the shape, can be divided into: flat-head tubular fuses (also can be divided into internal welding fuse and external welding fuse), pointed tubular fuses, guillotine-type fuses, spiral fuses, chip-type fuses, plate-type fuses, wrap-type fuses, SMD-type fuses.

According to the fuse speed, can be divided into: special slow fuse (generally with TT), slow fuse (generally with t), medium-speed fuse (general with M), quick fuse (general with F), special fast fuse (generally used in FF).

According to the standard points, can be divided into: European regulations fuse, the United States regulation fuse, the daily rule fuse.

According to type, can be divided into: current fuse (SMD fuse, miniature fuse, chip fuse, tubular fuse), temperature fuse (rh[block type], rp[resistor type), ry[metal shell], self-recovery fuse (plug, laminated, SMD).

According to the size can be divided into: SMD-type 0603,0805,1206,1210,1812,2016,2920; non-SMD type φ2.4x7,φ3x7,φ3.6x10,φ4.5x15,φ5.0x20,φ5.16x20,φ6x25,φ6x30,φ6x 32,φ8.5x8,φ8.5x8x4,φ10x38,φ14x51.
