- Fuse are designed to handle high fault currents and provide protection against short circuits and overloads in electrical systems.
- A fuse is not a power-limiting device; instead, it is a current-limiting device designed to protect electrical circuits from excessive current.
- The fuse element inside a fuse is typically made from a high conductivity material, such as silver or copper. This element melts when excessive current flows through it, breaking the circuit.
- Fuse is consistent & it has the feature like if it has a high fault current then break time is low. Similarly, if the fault current is not high, then break time is long.
- In normal conditions, the flow of current through the fuse doesn’t provide sufficient energy to soften the element. If the huge current flows through the fuse then it melts the element of the fuse before the fault current achieves the climax.
A fuse protects circuits by breaking the connection when the current exceeds a safe limit, but it does not directly control or limit power consumption in normal operation.
