ABSTRACT:
A DC circuit breaking spark suppressor device includes first and second main switch components having sequentially linked contacts for connecting a DC power supply to a main load, and a capacitor connected in parallel with the first switch component to store electricity when the first main switch component is opened, the second switch component being opened after opening of the first main switch component to disconnect the load from the power supply, after which the capacitor discharges through a discharge resistor. The discharge circuit includes a switch apart from said main switch components to isolate the discharge circuit prior to discharge, and an additional damping inductor. Alternatively, isolation of the discharge circuit may be achieved adding a contact to the second main switch component such that when the load is disconnected from the power supply, the discharge circuit is closed to cause the capacitor to discharge through the discharge resistor.
