What is a distinguishing characteristic of a "rejection" type fuse compared to a standard fuse?

A rejection type fuse is designed with a crucial feature that differentiates it from standard fuses: it cannot be replaced with a larger fuse beyond the fuse holder rating. This characteristic is vital for ensuring safety and preventing potential electrical issues. By limiting the size of the fuse that can be replaced, rejection type fuses help maintain the integrity of the circuit and protect against the risks associated with using a fuse that could allow too much current to pass through, which could result in overheating or damage.

In contrast, standard fuses do not typically have this restriction; they can be replaced with larger fuses, which can sometimes lead to dangerous situations if overcurrent protection is compromised. This safety feature makes rejection type fuses especially important in applications where precise electrical protection is needed.
