Morphology

electrical + fuse

The meaning is directly and transparently derived from 'electrical' (relating to electricity) + 'fuse' (a protective element that melts under overload), so a learner who knows both constituents will understand it refers to a device that interrupts electric current when overloaded. This adjective+noun composition is a common, cross-linguistic pattern and follows standard English noun phrase formation, making it readily comprehensible to a B1 learner.

Etymology

Electrical fuse comes from a simple image: a thin wire inside a small part that is meant to 'melt' when too much electricity flows. This makes the fuse 'break' the flow, so the name tells us it is a 'safety device' that stops electricity to protect wires and machines.
