Fuses

Fuses and circuit breakers are types of electrical components that protect electrical circuits against short circuits and overload. Fuses contain a small piece of metal or wire that melts when too much current passes through it, cutting off the circuit and preventing further damage. Circuit breakers, on the other hand, consist of a switch-like device that is opened when an overload occurs, and then reclosed when the overload is gone.

0HEV030.SXBD Application Field and Working Principle

0HEV030.SXBD is a high-speed marking fuse made by Fiting Corporation. It is mainly used for over-voltage, short-circuit, leakage and over-current protection in fields such as photovoltaic systems, air conditioners, cleaning machines, small motor systems, LED lighting, computers, communications and other electrical equipment. It has high sensitivity and can be quickly short-circuited, and it can restore itself after the overcurrent phenomenon is eliminated.

The 0HEV030.SXBD fuse is composed of two parts: an insulated sleeve and an inner conductor. The inner conductor is composed of silver-cadmium alloy wire. The silver-cadmium alloy wire is a high-conductivity, soft and malleable, low-melting-point wire. When the current passes through the wire, the heat generated by the wire increases, and when the current exceeds the rated current, the wire instantly melts and the circuit is short-circuited. This effectively protects the electrical equipment from the damage caused by overcurrent.

The rated current of 0HEV030.SXBD is 30A. Its size is relatively small and it is very convenient to install. It is mainly used in high power applications and is characterized by high speed, high temperature, high current and high sensitivity. It can be quickly short-circuited in a short time and it is also very reliable in use.

In order to use the 0HEV030.SXBD correctly, its position should be set correctly. When the fuse is installed, the connection between the fuse and the equipment must be kept tightly. When there is over-voltage, short-circuit, leakage and over-current, the 0HEV030.SXBD will quickly short-circuit and protect the circuit and electrical equipment.

In summary, the 0HEV030.SXBD is a high-speed marking fuse produced by Fitting Corporation. It is mainly used for protective purposes in application fields such as photovoltaic systems, air conditioners, cleaning machines, small motor systems, LED lighting, computers, communications and other electrical equipment. It has high sensitivity and can be quickly short-circuited when an overload occurs. This effectively protects the electrical equipment from further damage.
