3JQ 1.5-R TR

Fuses are an important part of electrical safety systems, and 3JQ 1.5-R TR is one type of fuse. It is suitable for a variety of applications in different fields and has a high resistance to over-pressure and short-circuit current.

3JQ 1.5-R TR fuse has many advantages, such as small size, low cost, long service life, easy use and so on. It has a fast response time, and the current carrying capacity is strong. The fuse is made of polymeric fortified insulation material that has excellent electrical insulation properties.

Application Fields

3JQ 1.5-R TR fuses have a wide range of applications. It is applicable for low-voltage, overload and short-circuit protection of various AC and DC power distribution circuits. The fuse can be used in telecommunications systems, telecommunication systems, audio and video systems, medical systems, DC power supplies, electric locks and other fields.

Working Principle

When the current in the circuit increases to a certain value, the current-sensing element of the 3JQ 1.5-R TR fuse generates heat due to the linear temperature increase with the current increase. When the heat generated by the fuse reaches the set value of the fuse, the fuse melts and breaks the circuit, thus achieving the purpose of protection.

The fuse provides a reliable, economical and efficient current protection homeostasis, and has a very simple structure. The internal structure of the fuse consists of a fuse element, a cylindrical tube and a lined cap. The fuse element is made of polymeric fortified insulation materials such as polyvinyl chloride, polyethylene, polyethylene terephthalate, epoxy resin, etc. The fuse element is heated when the current passes through, and when the heat reaches a certain temperature, it melts and breaks the circuit.

In conclusion, 3JQ 1.5-R TR is a widely used type of fuse that has many advantages, such as fast response time, strong current-carrying capacity, long service life and small size. It has a variety of application fields and can be used in low-voltage, overload and short-circuit protection of various AC and DC power distribution circuits. The fuse provides reliable, economical and efficient current protection.
