(1) The working principle of the fuse is mainly based on the thermal effect of the current. When the current exceeds the fixed value (the fixing value of different fuses is different), the internal fuse will cause the melting to break and the fuse to achieve the circuit. Circuit, and the protection ... Read More

(1) The fuse of the fuse can reach the microsecond (μs) level, that is, its speed is much faster than the circuit breaker. Installation and use. (2) The sliding movement speed of the circuit breaker is in milliseconds (MS). It can be seen that it is much slower than the fuse, so it can only be used ... Read More

(1) The protection method of the fuse is the form of a fuse. When the fault is eliminated, the fuse is required to replace the power supply, which is not convenient for maintenance. (2) The protection method of the circuit breaker adopts the form of a trip. After the failure is eliminated, the ... Read More

No. It should only be regarded as a nominal nominal specification, and what extent the current flowing through the fuse is large and when the melting is melted. Different. The fuse has a "fuse coefficient" value greater than "1" (usually between 1.1 and 1.5), which is the ratio of "conventional non ... Read More

1. Work current: In the environment of 25 ° C, the actual current with a rated current of less than 75%. 2. Use voltage: The rated voltage of the fuse should be greater than or equal to an effective circuit voltage. 3. Use ambient temperature: The higher environmental temperature fuse is relatively ...

Fast melting and slow melting fuses are often applied to different circuits because of their differences, such as: a fast melting fuse in the circuit of pure resistance circuit (no or rare) or sensitive devices such as IC The capacity or perceptual circuit (there is waves when the switch is turned ...

The main difference between fast melting fuse and slow melting fuse is its ability to withstand instantaneous pulse current. Technically, slow melting has a large melting thermal energy value. In terms of, slow melting is much stronger than the ability of fast melting pulse resistance. Because the ... Read More

In the strict sense, the temperature fuse refers to the component that can disconnect the circuit when the temperature of the temperature exceeds certain temperature. After the temperature fuse is turned on the circuit, its own internal structure has been damaged. Even when the temperature returns ... Read More

① The fuse must be replaced again when the fuse has been performed and the melting is melted. It can be reused again in the case of most of the case. ② The effects of the broken circuit breaker will be stronger than the circuit breaker. In general, the circuit breaker is installed on the sub -route. ... Read More
