Key features

High-performance 32-bit ARM microprocessor for real-time signal processing and intelligent control.

Three-stage protection (long delay/short delay/instantaneous) + comprehensive protection against overload, short-circuit, overvoltage, undervoltage, phase loss, and zero-sequence faults.

High breaking capacity ensures reliable short-circuit protection, with automatic reclosing and fast closing speed (<2s).

Chinese/English LCD display with user-friendly interface, supporting real-time voltage/current monitoring and fault record management.

High-precision measurement (0.5S class for voltage/current, 1 class for power), with real-time power monitoring and three-phase active power accumulation.

Supports four remote control functions (remote signaling/telemetry/control/adjustment) and online remote upgrades for easy maintenance.

Supports DL/T645 and Modbus protocols, with HPLC plug-and-play module and Bluetooth wireless communication for low-power operation.

Optional functions including time/cost control, temperature monitoring, passive islanding protection, and power quality monitoring to meet diverse needs.
