Circuit breaker (CB) to interrupt the load and fault current. The fault current automatically triggers the CB. Disconnect switch to provide visible circuit separation. Permit CB maintenance. No load operation. Voltage and current transformers to reduce the current to 5 A, and the voltage to 120 V, and to insulate the measuring circuit from the high voltage. Surge arresters for protection against lightning and switching overvoltages. They are voltage dependent, non linear resistance .
