Title:
物理的な開路接点構造を有する電子サーキットブレーカならびに禁止機能によるフェイルセーフ保護
Document Type and Number:
Japanese Patent JP6759441
Kind Code:
B2
Abstract:
A circuit breaker includes contacts movable between a closed position wherein a line terminal and a load terminal are in electrical communication, and an open position wherein the line and the load terminals are electrically isolated. A primary trip coil and a secondary trip coil are connected to the contacts, each causing the contacts to move from the closed position to the open position when activated, thereby tripping the breaker. A monitoring circuit, upon a determination being made that the breaker is not operating within acceptable trip parameters, causes activation of the primary trip coil, and, upon a determination being made that the breaker is not operating within acceptable disable parameters, causes activation of the secondary trip coil. The breaker is user resettable if the breaker has been tripped by the primary trip coil, but is not user resettable if the breaker has been tripped by the secondary trip coil.
