Fuse a wɔde besi ananmu .
Compared to another switchgear-like fuse, a circuit breaker is smaller in size and can be automatically reset for repeated operation. Fuses are made up of metal and are placed in the circuit for protection. Whenever heavy current flows through the circuit, the fuse melts or blows up. A fuse can be used only one time and cannot be reset post-repair of faults in the circuit. Every time a new fuse must be added to the circuit for a one-time operation. Moreover, fuses have slow capabilities to determine the time to start operation and are used for low-voltage applications. On the other hand, circuit breakers are fast enough to operate in faulty conditions. A circuit breaker can be automatically reset post-repair of the circuit and ensures continuous supply. Using a circuit breaker instead of a fuse eliminates the cost of replacement, saves time, and enables Adwumayɛ a ɛwɔ ahoɔden kɛse.
