Product Performance

Integrated with multiple fault protection functions, it can accurately identify fault types such as overload, short circuit and ground fault, with a trip response time of ≤50 milliseconds, effectively limiting fault expansion and reducing the risk of equipment damage.

±0.2% high-precision power measurement capability can real-time monitor key electrical parameters such as current, voltage and power, providing accurate data support for operation and maintenance and energy efficiency analysis of power distribution systems.

Compatible with multi-protocol communication and standardized interfaces, it can be seamlessly connected to intelligent power distribution automation systems to realize remote parameter setting, fault query and status monitoring, improving operation and maintenance efficiency.

Modular hardware design facilitates on-site function expansion and component replacement. The graphical operation interface with Chinese display simplifies the debugging process and reduces the operation threshold.

Wide temperature tolerance of -40℃ to +70℃ and IP54 protection level can resist high temperature, low temperature, dust and humid environments, adapting to complex power distribution scenarios such as industrial plants and substations.

Equipped with fault recording and event logging functions, it can completely trace the changes of electrical parameters before and after faults, providing a reliable basis for fault cause analysis and shortening fault troubleshooting time.

Supports online parameter setting and self-diagnosis functions, enabling parameter adjustment and fault early warning without shutdown, ensuring continuous operation of the power distribution system and reducing shutdown losses.

Multiple anti-interference designs comply with IEC 61000 series standards, which can effectively resist electromagnetic interference and voltage fluctuations, ensuring the reliability and accuracy of protection actions under complex working conditions.
