An indication of a type of circuit breaker through which a powered device is connected to a power source is received at a processor. A signal from a sensor indicating a level of power flow from the power source to the powered device is received at the processor. The power flow to the powered device is altered by the processor based upon the received signal and the type of circuit breaker such that the power flow does not cause the circuit breaker to interrupt the power flow to the powered device.

An electrical protection device, including a switching mechanism configured to switch between a set configuration and a tripped configuration, and a slide movable between a set position and a disengaged position. The electrical protection device further includes a resetting hook kinematically linked to a switching lever, and the slide supports a slide hook. When the slide is in the disengaged position, the resetting hook and the slide hook are ready to be engaged, and when the slide is in the set position, the slide hook and the resetting hook are spaced apart from each other and resetting of the electrical protection device results in engagement of the slide hook and the resetting hook and in a displacement of the slide.

The circuit breaking system contains a power circuit whose voltage is greater than 600 volts, at least a circuit breaking device, at least a current detection device, a current reduction unit, at least an actuation device, and a linking device. The circuit breaking system is applicable to a high or ultra-high voltage power circuit, and the power circuit is interrupted through purely mechanical means without additional electricity provision. Even when there are major disasters that existing protection means fails, the present invention can still function and provides a trip free, ultimate self-protection mechanism so that a power system can be readily reset.
