In which scenarios is a fuse more suitable than a circuit breaker?

A fuse is more suitable than a circuit breaker in smaller, less critical applications where cost and space are limiting factors because fuses are typically less expensive and take up less physical space compared to circuit breakers. They provide adequate protection for low to moderate current applications and are particularly effective in scenarios where the overall risk is lower and the need for regular access to the protective device is minimal.

Fuses operate by melting a conductive element when the current exceeds a certain level, which provides a clear and definitive point of failure. This can be beneficial in applications where space is confined, as fuses can be made compact and usually require less installation space than circuit breakers, which may be bulkier due to the mechanical components required for their operation.

In contexts where the device is not frequently accessed or reset, such as in many home appliances or small electronics, fuses offer a simple, cost-effective solution. This makes them a practical choice for protecting less critical systems without the additional expense or complexity associated with circuit breakers.
