PROTECTION AND COMMAND MODULE FOR ELECTRICAL SYSTEMS AND APPARATUS

摘要

This invention concerns a protection and control module for unipolar, bipolar or multipolar electrical systems that includes a detection device or sensor (3) configured to detect both the absorbed and the dispersed current by the electrical line it is connected up to and to send signals to a management and control device (5) indicating any possible amperometric and differential faults, and a power device (4) comprising a zero crossing circuit to supply, in the case of operating using alternating current where the feed signal has a sinusoidal form, the management and control device (5) with a changeover signal of a relative power stage only on the zero crossing of the current so as not to supply tension where a connected load to the electrical line is lacking.
