Earthing switch/ earth switch, also known as ground switch or grounding switch, is an electrical safety mechanism that is considered crucial in circuit breakers. Once a circuit breaker is cleared and racked out, the bus bar sections adjacent to the circuit breaker are automatically earthed through these switches device. This event safeguards the maintenance personnel from any possible accidental voltages.
The closing activity of a ground switch/grounding switch is called a snap action type, making it dimensioned to withstand short circuit currents. Also, the earthing switch is commonly used with isolators and can be motorized. Whenever the isolator isolates the circuits, the earthing switch/earth switch contacts the busbar and discharges any accumulated power current whenever the isolator isolates the circuits.
