Title:
PARALLEL CONNECTION BREAKER
Document Type and Number:
Japanese Patent JPS59196525
Kind Code:
A
Abstract:
A circuit breaker comprising two or more sections connected in parallel with each other. Each section of the circuit breaker comprises an electromagnetic sensing device and a pair of relatively movable contacts. The electromagnetic sensing devices are electrically connected at one of their ends to the load terminals. The load terminals are electrically connected in parallel with each other. The electromagnetic sensing devices are electrically connected at their other ends to each other and are electrically connected to all of the movable contacts which are themselves all electrically connected together. The stationary contacts are connected to line terminals which are also electrically connected in parallel with each other. Thus, the electromagnetic sensing devices are connected in parallel at both of their ends and the relatively movable contacts are also connected in parallel at both of their electrical ends while the electromagnetic sensing devices, on the one hand, and the movable contacts, on the other hand, are also in series with each other, whereby the current is divided equally among all of the electromagnetic sensing devices even though the current may not be equally divided among all of the relatively movable contacts, because of varying contact resistances.
