company news about What factors affect the performance of fuse?

      Fuse in the IEC127 standard defines it as "fuse link". It is an electrical component installed in the circuit to ensure the safe operation of the circuit. Fuse is actually a short circuit protector, widely used in power distribution system and control system, mainly for short circuit protection or serious overload protection. The specification of the selected fuse is different from the requirements of the actual application circuit;

• ---European specification and American specification: the performance varies greatly, even contradicts;
• ---Fast break and slow break: the ability to withstand pulse is different (I²t);
• ---Breaking capacity and withstand voltage: affecting safety performance;
• ---Fuse resistance value: affects the output power and power consumption;
• ---Contact resistance value: affect the action time and speed of fuse;
• ---Ambient temperature: affect the action time and speed of fuse;
• ---Heat dissipation conditions: affect the action time and speed of fuse;
• ---Fuse parallel connection: the rated voltage remains unchanged, the rated current is added, and the action time is slightly prolonged;
• ---Fuse series connection: rated voltage is added, rated current is unchanged, and has no practical significance
