Abstract
The module comprises a metal enclosure constituting a metal-clad housing receiving a multipole circuit-breaker and disconnector units where disconnection is performed by tilting the set of poles away from an in-service position in which each pole is simultaneously connected to two current feedthroughs projecting through the top wall of the housing. The distribution substation comprises a metal enclosure constituting a metal-clad housing that is subdivided into compartments serving specifically to house three multipole circuit-breaker and disconnector units in parallel alignment between two feeders. The poles of the units are interconnected via current feedthroughs passing through intermediate compartments, each of which has a feeder terminating therein.
