Abstract

The circuit-breaker has a magnetic circuit that consists of a yoke with a trip coil wound around one arm and a permanent magnet rivetted to another arm. A lamination is also rivetted to the permanent magnet and forms the knife-edge support for a spring-tensioned rocking arm which spans the two arms. A part of the yoke between the two arms is fixed to the housing and its base, which are sealed by ultrasonic soldering. This method of construction and fixing prevents external pressures or temperatures affecting this very sensitive circuit-breaker which has close operational limits.
