ELECTRICALLY OPERATED BRANCH CIRCUIT PROTECTOR

摘要

Electrical operation of circuit breakers utilizing a straight pull dc magnet system with positive means of locking in OFF position is provided. The operating dynamics have advantages in fault coordination and discrimination for motor branch circuits. The construction offers physical and economic advantages in control solutions.
