<p>Switchgear modules (D), including e.g. circuit-breaker, control and indication units, fit closely against each other on a common mounting rail (1). Their supply-side terminals (2) are located on one narrow face (4), outgoing terminals (3) on the other (5). The supply-side connections are completed by the teeth (9) projecting in two staggered rows from line and neutral busbars consolidated in an insulated structure (6) running parallel to the rail. Each tooth enters a socket (C), rectangular in section, in the module moulding, and is pressed against a contact, forming one side of the socket and over which it slides, by a U-spring (11), one leg of which (12) is fixed to the tooth while the other (13) slides over the opposite side of the socket.</p> |
