Key Features

  • 【High-Quality Material】: The casing of this adjustable voltage and current protector is made from high fire-resistant PC material, which is not prone to combustion, ensuring safe usage. It boasts sensitive operation, precise measurement, and minimal heat generation. Its aesthetically pleasing design showcases excellent craftsmanship.
  • 【Multiple Functions】: As a voltage and current protector, it features functions such as overcurrent, overvoltage and undervoltage protection. When the current/voltage deviates from the set value, the relay automatically disconnects the power to prevent fires and safeguard electrical devices. It also has an auto-reset function, which means that when the voltage and current return to normal values, the power is automatically restored.
  • 【Note】: During AC power supply, the equipment can protect both voltage and current; during DC power supply, the current display is not shown, and "DC" appears in the current display position, with the equipment only protecting voltage.
  • 【Easy Installation】: Adopting a rail-mounted design simplifies the installation process, saving time and labor costs. Moreover, it enables easy adjustment and movement of the equipment to meet diverse installation needs and spatial requirements.
  • 【Versatile Applications】: The protector has a wide range of applications in various electrical devices and systems, ensuring the normal operation and safety of equipment. For instance, they are used in motor protection, electrical control systems, household appliances, industrial equipment, lighting systems and more.
