Installation location: The three-phase switch should be installed in a well-ventilated, dry, non-corrosive gas and limited dust environment, away from flammable and explosive materials.

Insulation and marking: The switch should have sufficient electrical insulation and be properly marked with voltage level, current capacity and phase information.

Regular inspection: Regularly check the status of the switch, including observing whether there are signs of overheating, burning or other abnormalities, to ensure its normal operation.

Operator Training: Only trained and skilled personnel can operate the switch to avoid potential hazards.

Remote and automated systems: Where possible, remote and automated systems should be considered to reduce direct operator intervention and increase safety.

Emergency stop: An emergency stop button or switch must be provided to cut off power immediately in a hazardous situation.

Regular maintenance: regular maintenance and maintenance of three-phase electric switch, including tightening connections, cleaning, lubricating and replacing worn parts.

In conclusion, following these safety requirements can reduce the risk of switch failure and power system accidents, ensure the safe operation of the power system, and protect the lives and property of operators.
