<p>Automatic and self-sustaining electronic system for the early detection of short-circuit fault conditions which consists of a solid-state switch formed by a power supply block and a control block, via which an optocoupler which is able to receive and differentiate between electrical signatures is activated, the arrangement of which makes it possible to recognize the type of fault condition (short circuit), to interrupt the current and to restore the latter automatically or manually without electric arcs, without a fall in the threshold and without heat dissipation, thus increasing the service life, reducing the response time and restoring the operation of the installation or electrical apparatus to be protected.</p> |
