Safety and Protection
Low-voltage circuit breakers offer automatic disconnection in case of overload or short circuits, preventing damage and fires.
All three components contribute to a safer electrical environment, protecting both property and individuals. -
Reliability and Stability
Integrated protection functions in circuit breakers, such as leakage and overvoltage protection, enhance the reliability of electrical systems.
Surge protectors improve the stability of critical equipment and systems by reducing the impact of voltage fluctuations. -
Efficiency and Energy Conservation
Prompt disconnection of overloaded circuits by circuit breakers helps in saving energy and reducing waste.
-
Maintenance and Cost Reduction
The ease of maintenance of low-voltage circuit breakers reduces service costs and downtime.

What are the main types of electric meters?
Electromechanical (Induction) Meters: Use electromagnetic induction to drive a rotating disk. Simple but vulnerable to environmental interference (e.g., humidity, thunderstorms).
Electronic Meters: Utilize electronic components for measurement, offering advanced features like prepayment, time-of-use billing, and anti-reverse flow. Require anti-interference design to prevent data errors. -
How do I choose the right electric meter?
Current Rating: Select based on basic current (e.g., 5A) and maximum rated current (e.g., 20A) to avoid overload damage.
Functionality: Match features like prepayment, networked meter reading, or anti-reverse flow to your needs.
Accuracy Class: Common classes include 0.2S, 0.5S, 1.0, and 2.0 (higher = more precise). -
What preparations are needed before installing an electric meter?
Ensure the location is well-ventilated and free of corrosive gases.
Gather tools: wrench, screwdriver, insulating tape, etc.
Turn off power before connecting inlet and outlet wires securely. -
How to detect electrical leakage?
Use an insulation resistance tester to check the meter and wiring. Low resistance indicates leakage.
