Product Performance

High-Precision Protection Operation: Current and voltage measurement accuracy reaches ±0.2%FS, and overcurrent instantaneous operation time is ≤0.05s, which can accurately identify faults and respond quickly to prevent equipment damage caused by fault expansion.
Multi-Protection Function Integration: Supports 6 types of core protection functions including overcurrent, overvoltage, undervoltage, and frequency abnormality simultaneously, no additional protection modules required, simplifying the design of distribution system protection schemes.
Strong EMC Immunity: 2500Vrms high isolation design between power supply and signal terminals, combined with an electromagnetic shielding shell, can resist surges, harmonics, and electromagnetic radiation interference in distribution sites, with protection action false operation rate ≤0.01 times/year.
Wide Environmental Adaptability: The operating temperature range of -40°C to +70°C covers alpine and high-temperature areas, and the IP54 protection class can resist dust and splashing water, adapting to complex environments such as outdoor distribution rooms and industrial workshops.
Intelligent Data Management: Built-in ≥1000 fault records function, which can store electrical parameter snapshots when faults occur, supporting data export through communication interfaces to assist operation and maintenance personnel in tracing fault causes and shortening troubleshooting time.
