Q: The main parameters of the fuse selection: The voltage rating of the fuse must be greater than or equal to the maximum voltage of the disconnect circuit.

Q: What is the principle of choosing a fuse?: he limit breaking current of the fuse should be greater than or equal to the effective value of the short-circuit impulse current that may occur in the protection circuit

Q: What is the melt of the fuse?: Melt is often filamentous, flaky and grid-like, is the main component of the fuse, according to the size of the thermal inertia of the melt can be divided into non-thermal inertia of the melt, hot inertia of the melt and small thermal inertia Melt.

Q: What is the difference between the breaking capacity of the fuse and the fusing capacity: Fuse characteristics of the fuse overload test, requiring the fuse in the overload test, the fuse fuse time to the standard within the range

Q: What parts are the fuses divided: The fuse is composed of insulation base (or support), contact, melt and so on.

Q: What is the installation of the fuse.: If there is a starting current in the circuit, the starting current is normal in some circuits. In this case, the delay type and the medium delay type fuse tube should be used.

Q: What is the fuse often used?: General fuse consists of three parts: First, the melt part, it is the core of the fuse,

Q: Is the fuse blown depending on the size of the current flowing through it?: Only in this way the fuse can be safe and effective work, otherwise, in the fuse fuse will appear continuous arcing and voltage breakdown and harm the phenomenon of the circuit.

Q: Use a multimeter to check if the fuse is damaged: The choice of motor fuses is generally 2-2.5 times the rated current

Q: What is the use of the fuse?: Low-voltage distribution system fuse is a security role in the protection of electrical appliances,
