turning power on and off to a particular device. A circuit breaker, on the other hand, can be used to protect a circuit that contains many switches or devices. An exception to this is a disconnect switch, which is used to connect or disconnect power to an entire control panel, or machin...
A disconnector switch or isolated phase busbar circuit breaker, comprising: a hollow external conductor at ground potential; a fixed internal conductor of two parts at high potential, supported with insulation inside said external conductor and concentric with it; a high potential mobile internal ...
Control device for the discharge and the decoupling of an energy accumulator during the disconnection of a disconnectable circuit breaker The invention concerns a switching device with an arrangement for controlling the movability of a plug-in circuit-breaker (2) relative to a plug-in frame (.....

. There is therefore selectivity between two circuit-break- ers in series when, for an overcurrent which passes through both, the load-side circuit-breaker opens thereby protecting the circuit, whereas the supply-side one re- mains closed guaranteeing power supply to the rest of the installation...
A circuit for actuating a circuit breaker to disconnect a load from across conductors connecting the load across an input circuit which has one neutral side upon the occurrence of an imbalance in the currents flowing in the conductors. The circuit includes a differential transformer having a bifilar...
while ROUTis placed near the monitoring electronics without ground drop errors. This circuit has a fast 1µs response time that makes it ideal for providing MOSFET load switch protection. The switch element may be the high side type connected between the sense resistor and the load, a low ...
Fast and hard switching action in DC current interruption causes excessive voltage across the circuit breaker. This paper investigates a new type of solid-state DC circuit breaker namely current releasing DC circuit breaker. The mechanism of current interruption in the current releasing DC circuit ...

In dual-breaker applications stub-bus protection is best accomplished by enabling a low-set differential overcurrent element when the disconnect switch is open. With security inherent in the differential principle, differential-based stub-bus protection is very fast. If a simple overcurrent element ...
