Basic functions of protection relays

The protection relay is an indispensable component in modern electrical systems. Its main functions include overload protection, short-circuit protection and undervoltage protection. These functions play a vital role in different circuit environments to ensure the safe operation of electrical systems. Whether it is industrial automation production lines, or home circuits and power systems, protective relays can effectively prevent potential risks and ensure the safety of equipment and personnel.

Excellent technical parameters

Our protective relays have excellent technical parameters, making them far ahead in performance. The following are some key technical parameters:

• Rated voltage: 220V AC / DC
• Action current: 1A-10A
• Response time: ≤ 10ms
• Operating temperature:-20°C to +70°C
• Protection class: IP65

Through these parameters, you can clearly see the adaptability and stability of the protection relay in various environments. Whether it is high temperature, low temperature or humid environment, it can perform well.

Practical Application Case Study

Protection relays are widely used in many fields. The following are a few typical practical application cases to help you better understand its actual value:

Industrial Automation Production Line

On the automatic production line of an automobile factory, due to the long-term high-load operation of the equipment, overload and short circuit are prone to occur. After the protection relay is installed, the power supply can be cut off in time to avoid equipment damage and production interruption, which greatly improves the stability and safety of the production line.

Home circuit

In an ordinary family, the kitchen and bathroom circuits often cause accidents due to moisture and overload. After the protection relay is installed, the power can be cut off immediately when an abnormality is detected, protecting the personal safety and property safety of the family.

Power System

In the power grid of a certain city, power outages and fires often occur due to lightning strikes and aging lines. By installing protection relays, the status of the power grid can be monitored in real time, faults can be found and handled in time, and the normal operation of the entire power system can be ensured.

User Reviews and Success Stories

Since its listing, the protection relay has been highly praised by the majority of users. Mr. Wang said: "Since the installation of the protective relay, my family's circuit has never had any problems. I am very relieved."
