Control and protective switching JGKB-45

Introduction

   The new control and protection switch has a beautiful appearance design, and the product has functions such as overvoltage, undervoltage, overload, short circuit, locked rotor, three-phase imbalance, over temperature, leakage, communication, etc. The software design is user-friendly, with direct three row display, and the product's functions are easy to expand. Currently, it is the most comprehensive control and protection switch in the protection function of electrical protectors.

 Product features

1. Function extension: Temperature and leakage protection, as long as external accessories are connected, the required protection functions can be added

2. Three row digital tube display, real-time voltage, current, leakage, and temperature parameters display intuitively

3. Wide adjustable range of protection current:

                                       10A： 1-10A

                                       45A： 2-45A

                                       125A： 32-125A

4. Customizable 485 communication function

5. Password function to prevent unnecessary after-sales service caused by unauthorized personnel setting the product incorrectly on site

6. Added factory recovery function, which allows for one click recovery to the original program state in case of on-site setting errors
