Device for supplying electric power to electrical power equipment modules such as circuit-breakers, and breaking apparatus adapted for use in such a system

摘要

The modular electrical power feed has circuit breakers mounted side by side on a rail with secondary connector bars forming electrical connection between the modules. Electrical contact is formed by pin contact with one of the pins (11) partially covered by an electrically isolating piece (12). the electrical isolating piece prevents contact with an incorrect connection due to fingers probing into the area, whilst allowing access to electrical apparatus (1).
