Three-Display Control And Protective Switching Device, Function Extended Type | Motor Protector | Motor Phase Failure Protector | Motor Protection Device Jgkb-45 (Cps) Product Image

Three-Display Control And Protective Switching Device, Function Extended Type | Motor Protector | Motor Phase Failure Protector | Motor Protection Device Jgkb-45 (Cps)

The new three-display control and protection switch adds temperature and communication functions to the original feature set. The single-row display has been upgraded to a three-row display, the product adopts a modular design, and the software is more user-friendly. If over-temperature protection and leakage protection are needed during use, simply connect external sensors and enable the temperature and leakage functions in the secondary menu, making it convenient to expand with optional functions. It also supports Modbus 485 communication, sending data to a backend monitoring system to realize the five remote functions: remote metering, remote signaling, remote control, remote adjustment, and remote video monitoring. Product Features: 1. Function expansion: temperature and leakage protection—simply connect external accessories to add the required protection functions. 2. Three-row digital display provides an intuitive real-time display of voltage, current, leakage, and temperature parameters. 3. Wide adjustable protection current range: 2-45A. 4. Customizable 485 communication function. 5. Password function prevents unnecessary after-sales service caused by incorrect settings made by unauthorized personnel on site. 6. New factory reset function: if settings are configured incorrectly on site, the device can be restored to its initial program state with a single key press.

VI. Typical Applications

When the JGKB is in the free-trip operating state, i.e., the knob arrow is at the "Trip" position, after the fault is cleared, turn the knob to the reset position, i.e., the "Reset" position. After resetting, the knob should automatically return to the open position, i.e., the "Open" position. Then turn the knob to the "Close" position, and the JGKB can connect the main circuit and achieve remote automatic control.
