  • Patent number: 4468531
    Abstract: A safety shield assembly for insertion within a drawout circuit breaker compartment between the load and line receivers in the compartment and the power stabs on the circuit breaker. The shield assembly utilizes a moveable shield, a pair of spring motors and a pair of actuating probes to operate the shield. One spring motor and one actuating probe are attached on either side of the circuit breaker compartment and both probes must be actuated before the spring motors can draw the moveable shield into an open position to expose the line and load receivers. The probes include a compression spring at its point of contact with the circuit breaker to compensate for overtravel.
