Unlike a conventional circuit breaker with only two positions (ON/OFF), this design provides four fixed positions : ON, OFF, OFF-Disconnected, and Earthed. This allows for visible disconnection and grounding of the line side without additional hardware, simplifying substation design. However, the standard design required manual padlocking for the "OFF-Disconnected" position, a limitation that subsequent patents addressed with remote-operated blocking systems for enhanced safety.
