Home protector 220V Product Description
Home Voltage protector 220V is mainly suitable for household circuits. Since it can maintain the voltage value in the circuit in a relatively stable state, it plays a certain protective role for the electrical appliances in the circuit. This is the main function of a Voltage protector.
In the circuit, electrical appliances often have an instantaneous overvoltage due to abnormal power transmission from the power grid. In a very short time, the electrical appliances in the circuit are the first to be damaged, especially those that are working normally. The reaction of devices such as circuit breakers is relatively slow, and they often trip after the electrical appliances have been damaged, which is very detrimental to the stability of the circuit.
Home Protector 220V can protect the circuit from the fluctuation of the circuit voltage the first time, shunt the current, and make part of the current flow into the overvoltage protector for consumption so that the voltage in the circuit will be reduced and reach a normal working state.
Home voltage protector is a voltage protection device designed to protect home appliances from voltage fluctuations, surges, and power disturbances. It can effectively protect the following types of electrical equipment:
1. Home appliances
– Refrigerators: prevent damage to the compressor caused by voltage fluctuations.
– Air conditioners: protect motors and circuit boards from voltage surges.
– Washing machines: avoid motor and control panel failures caused by unstable voltage.
– Microwave ovens: protect internal electronic components from voltage fluctuations.
2. Electronic devices
– TVs: prevent voltage fluctuations from damaging the screen and internal circuits.
– Computers: protect motherboards, hard drives, and other sensitive electronic components from power disturbances.
– Audio systems: avoid damage to audio equipment caused by unstable voltage.
3. Small appliances
– Coffee machines: protect heating elements and control circuits.
– Rice cookers: prevent uneven heating or damage caused by voltage fluctuations.
– Electric kettles: protect heating elements and thermostats.
4. Office equipment
– Printers: prevent voltage fluctuations from damaging internal circuits.
– Router: Protect network devices from power interference and surges.
5. Other devices
– Lighting equipment: Extend the life of lamps and avoid damage caused by voltage fluctuations.
– Charging equipment: Protect the batteries and circuits of charging devices such as mobile phones and tablets.
Notes:
Power matching: Ensure that the Home voltage protector’s rated power can cover the total power requirements of the connected appliances.
– Correct installation: Install correctly according to the instructions and ensure that the equipment is well grounded.
– Regular inspection: Regularly check the working status of the home appliance protector to ensure its normal operation.
Using a home appliance protector, you can effectively extend the service life of electrical equipment and reduce damage and repair costs caused by voltage problems.

FAQ
What are the advantages of brass contacts compared with other material contacts?
| Performance indicators | Brass contacts (CuZn37) | Phosphor bronze contacts (C5191) | Silver-plated copper contacts |
| Conductivity (MS/m) | 15.5 | 18.2 | 62.5 |
| Hardness (HV) | 145 | 175 | 80 |
| Arc resistance | 3,200 Times | 4,500 Times | 6,800 Times |
| Cost ratio | 1.0x | 1.8x | 3.5x |
Technical advantages explained:
Economic adaptation:
Using lead brass (CuZn39Pb3) contacts, while ensuring a plug-in life of 10,000 times, the cost is reduced by 43% compared to the phosphor bronze solution (based on LME metal futures prices)
Environmental adaptability:
Through the 72-hour salt spray test (ASTM B117 standard), the surface oxide layer impedance only increased by 7.2% (23% for silver-plated contacts), suitable for high-humidity environments such as seaside
Safety redundant design:
The contact pressure design value reaches 8.5N (IEC 60884 requires ≥4N), and reliable contact can be maintained even if the elasticity decays by 30%
