Abstract
A shutter assembly is provided for an electrical system including at least one withdrawable electric apparatus, such as a circuit breaker, and an electrical bus member. A protruding structure of the circuit breaker is removably coupled to a corresponding primary contact of the electrical bus member to electrically connect the circuit breaker and the electrical bus member. The shutter assembly includes a pair of cover members that each have a ramped engagement surface and that are movable between a first position in which the corresponding primary contact of the electrical bus member is isolated and a second position in which the cover members are offset from the primary contact to allow the circuit breaker to be connected with the primary contact and the electrical bus member.
