Abstract: A load connector module for connecting a multi-phase load to a circuit interrupter which includes all the multi-phase connectors, a current transformer for each respective phase, and a voltage transformer coupling, in an integral, solid, insulated unit.

Abstract: A compact switchgear system employing a number of modular components that plug into their mating interface and are maintained in electrical isolation employing solid insulation in a manner that substantially shields the electrical conducting portions of the assembly from contact with lower voltage portions of the system. The assembly is primarily made up of five modules.

Abstract: A modular three position vacuum isolator switch that is operable to connect a stationary contact to either of two moveable contacts or an intermediate position which is out of electrical engagement with either of the moveable contacts. One of the moveable contacts is grounded and the other is connected a power source. The stationary contact is connected to two electrical connectors. One of the two electrical connectors is connected to a breaker and the second is connected to a corresponding input on a second similar isolator switch model, which itself is connected to a second line source. The stationary contact is connected to the circuit interrupter for connecting the circuit interrupter to either of the two line sources, to ground, or to isolate the circuit interrupter by placing the isolator switch module in the intermediate position.
