noun
Technical term for a fuse in electrical circuits; a safety device that melts to break the circuit when current is excessive.
過電流が流れると可溶片が溶けて回路を遮断する。
When an overcurrent flows, the fuse melts and breaks the circuit.
ヒューズ is the common loanword for 'fuse' in everyday and technical contexts. 可溶片 is a more formal, kanji-based term used mainly in technical documentation or older texts.
Compound of 可溶 (soluble, fusible) and 片 (piece, fragment), literally 'fusible piece'. The variant 可鎔片 uses 鎔 (melting, casting) instead of 溶.
