Title
(EN) PROTECTION ELEMENT AND PROTECTION CIRCUIT
(FR) ÉLÉMENT DE PROTECTION ET CIRCUIT DE PROTECTION
(JA) 保護素子および保護回路
Abstract
(EN)
This protection element has a first fuse element and a second fuse element connected in series. The protection element is configured such that, when an overcurrent flows to the first fuse element and the second fuse element, the first fuse element is cut off before the second fuse element.
(FR)
La présente invention concerne un élément de protection comportant un premier élément fusible et un second élément fusible connectés en série. L'élément de protection est configuré de telle sorte que, lorsqu'une surintensité circule vers le premier élément fusible et le second élément fusible, le premier élément fusible est coupé avant le second élément fusible.
(JA)
保護素子は、直列接続された第1ヒューズエレメントおよび第2ヒューズエレメントを有する。保護素子は、第1ヒューズエレメントおよび第2ヒューズエレメントに過電流が流れたときに、第1ヒューズエレメントが第2ヒューズエレメントよりも先に遮断されるように構成されている。
