Abstract
There is provided by this invention a novel switchgear shutter design employing curvilinear displaced shutter means which provide an entirely metallic grounded surface between the potentially live contacts and the front of the compartments. This novel shutter means is disposed to move to a safe and effective distance away from live electrical ports when the circuit breaker is moved into its normal operating position.
