When electrical current flows through a circuit, the fuse relay monitors the amount of current passing through it
. Under normal conditions, the fuse remains intact, allowing current to flow freely. However, if the current exceeds a predetermined threshold due to an overload or short circuit, the fuse element heats up and melts, breaking the circuit and preventing further damage.4. Worker Safety and Comfort The quieter operation of electric backhoes not only reduces noise pollution but also enhances worker safety and comfort. Operators are less exposed to engine noise, enabling better communication and awareness of surroundings. Furthermore, reduced vibration levels improve overall ergonomics for the operator.

Protective relays are devices that monitor electrical parameters and detect abnormalities, such as overcurrent or overvoltage conditions. When a fault is detected, relays send signals to circuit breakers to trip and isolate the affected section. This quick response helps protect vital equipment and minimizes disruptions to the power supply.
