    摘要: An electric circuit breaker comprising a switch, an arc extinguishing chamber and a fuse configured to be electrically connected between first and second terminals after the switch has tripped, further comprises a connection device comprising a gate configured to be broken after the switch has tripped only when at least one of the temperature, the pressure inside the arc extinguishing chamber or the intensity of an electrical arc present in the arc extinguishing chamber passes a predefined threshold, the connection device being configured to connect an electrode of the fuse to one of the terminals of the electrical conductor only once the gate is broken.

    摘要: A tool for the removal or installation of a fuse includes a first tool arm and a second tool arm pivotally mounted to the first tool arm about an axis. A second fuse holder spreader finger section is movable away from a first fuse holder spreader finger section and a second fuse pusher finger section is movable toward a first fuse pusher finger section in response to a first handle section being moved toward a second handle section.
