Fuses are one of the most widely used safety components in our lives. They are mainly used in low and medium voltage electrical systems to provide overload, short circuit and ground fault overcurrent protection. The 0SFE07.5VP application field and working principle is a type of fuse device, which is widely used in electrical power distribution and electrical equipment for short circuit and overload protection.

0SFE07.5VP, as a fuse, belongs to the breaking current type protective device. Its operating principle is that when an overcurrent or short-circuit appears in the circuit, the fuse element will soon heat up due to its thermal effect, melt, then disconnect the circuit, and achieve the purpose of isolation and protection.

0SFE07.5VP is mainly applicable to indoor AC 50/60Hz, rated voltage up to 400V, DC voltage up to 250V, rated current 7.5A circuit for short-circuit and overload protection, and it can also be used in various places as the secondary protection such as power distribution control cabinet and electrical equipment.

The standard 0SFE07.5VP fuse with a rated current of 7.5A, melting time of 4 hours or less (at 500% of its rated current), and breaking capacity of 20000A, is the most common type of fuse used in everyday electrical systems. Such fuses may be installed in the portable power tools or machines, lighting circuits and power circuits of home appliances.

In order to ensure the safe use of 0SFE07.5VP fuses, consumers must observe the safety regulations, closely control the current of the circuit, and promptly replace the fuses when they find them damaged or broken. In addition, the fuse must be of appropriate size for the protection of the circuit, which means the current specification of the current must be greater than the full load current of the electrical equipment and not more than the rated currentof the fuse.

It is generally recommended that the secondary protection of transformer, ballast, capacitor, soft starter, and other power electronic equipment should be 0SFE07.5VP fuse. Therefore, 0SFE07.5VP is a type of breaker-type short-circuit and overload protector with both safety and reliability.
