Automatic Voltage Protector (AVP) vs. Leakage Protector: A Big Reveal of Home Safety Devices

In the field of household electrical safety, voltage protectors and leakage protectors are two common devices, but many people cannot tell the difference and purpose between them. This article will deeply analyze the functions, applicable scenarios, and purchase recommendations of these two devices to help users build a more comprehensive safety line for their families.

I. The core difference between voltage protectors and leakage protectors

1. Different functional positioning

- Voltage protector: Mainly used to monitor and stabilize voltage to prevent damage to electrical appliances caused by excessive or low voltage. For example, when the voltage suddenly rises to 250V, the voltage protector will automatically cut off the power supply to prevent electrical appliances from burning.
- Leakage protector: Focus on detecting leakage current to prevent human electric shock or electrical leakage from causing fire. When the leakage current is detected to exceed the safe value (usually 30mA), the leakage protector will quickly cut off the power.

2. Different protection objects
- Voltage protector: Protect electrical equipment, extend the life of electrical appliances, and avoid damage caused by unstable voltage.
- Leakage protector: protects personal safety and prevents electric shock accidents, especially suitable for families with elderly and children.

3. Different working principles
- Voltage protector: monitors voltage changes in real-time and automatically adjusts or cuts off the power supply when abnormal.

- Leakage protector: detects the current difference in the circuit to determine whether there is a leakage risk.

II. Applicable scenarios: How to choose suitable equipment?

1. Applicable scenarios of voltage protector

- Areas with unstable voltage: such as old residential areas and rural areas, where voltage fluctuations are large and electrical appliances are easily damaged.
- Concentrated use of high-power electrical appliances: When high-power electrical appliances such as air conditioners, refrigerators, and washing machines are running at the same time, the voltage protector can stabilize the current.
- Thunderstorm-prone areas: The voltage protector can prevent voltage surges caused by lightning strikes and protect electrical appliances.

2. Applicable scenarios of leakage protector
- Humid environment: such as bathrooms, kitchens, and other areas prone to leakage.
- Families with elderly and children: prevent electric shock accidents caused by accidentally touching electrical appliances or sockets.

- Families with old electrical appliances: Old electrical appliances may have insulation aging problems and a higher risk of leakage.

III. The synergy between voltage protectors and leakage protectors

In actual use, voltage protectors and leakage protectors are not a "choose one or the other" relationship but can be used in a complementary manner to provide more comprehensive safety protection for the family.

- Case: A family installed two devices at the same time. The voltage protector prevents electrical appliances from being damaged due to unstable voltage, and the leakage protector avoids electric shock accidents. The double protection makes the family feel more at ease.

IV. Guide to Purchasing Home Safety Equipment

1. Purchasing Recommendations

- Voltage protector: Choose a model with fast response speed (≤0.1 seconds) and load power suitable for family needs, such as 5000W or more.
- Leakage protector: Choose a product with an operating current of ≤30mA and national 3C certification to ensure safety and reliability.

V.Conclusion: Electricity safety is the cornerstone of family happiness

A voltage protector and a leakage protector cost less than the cost of a dinner party, but they can protect family safety 365 days a year. Whether for personal use or as a gift, it is a tribute to women's wisdom and responsibility.
