Product Performance​

• Powerful protection functions: It has three – phase non – directional overcurrent protection (including timing or IDMT characteristics, low – setting stage, high – setting stage, instantaneous stage), non – directional earth – fault protection (with timing or IDMT characteristics, divided into low – setting stage and high – setting stage), phase discontinuity protection, three – phase cable thermal overload protection, arc protection, etc.​
• Automatic control functions: It has a three – phase multi – shot auto – reclose function suitable for overhead line feeders; breaker failure protection, a trip counter for breaker status monitoring, trip circuit monitoring and the ability to route warning signals to the signal output, and a trip lock – out function.​
• Accurate measurement and recording: It is equipped with four accurate current inputs; the disturbance recorder can record for up to 80 seconds, triggered by one or more internal or digital input signals, and can record four analog channels and up to eight user – selectable digital channels with an adjustable sampling rate.​
• Good human – machine interaction: The human – machine interface includes an alphanumeric LCD and navigation buttons, eight programmable LEDs, supports multiple languages, and users can select password protection for it. It can display primary current values and demand values, and all settings can be modified via a PC.​
• Flexible communication configuration: The optical front – end communication connection supports wireless or cable methods; it has an optional rear – end communication module that can be connected via plastic optical fiber, combined optical fiber (plastic and glass), or RS – 485 for system communication using SPA bus, IEC 60870 – 5 – 103, or Modbus (RTU and ASCII) communication protocols; it also has an optional DNP 3.0 rear – end communication module connected via RS – 485 for system communication using the DNP 3.0 communication protocol.​
• Reliable operation guarantee: It has a backup battery for the real – time clock and battery charging monitoring function; the electronic equipment and software are continuously self – monitored; it has the function of automatically adjusting the reference level according to the backlight intensity.​
