Cbrm5encl 630A Automatic Recloser MCCB IoT-Enabled Smart Circuit Breakers

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

Three-stage protection (long/short delay & instantaneous) with electronic trip, independent of power supply voltage, covering overload, short-circuit, overvoltage, undervoltage, and phase loss.

Real-time measurement of residual current, three-phase voltage/current, active/reactive/apparent power, power factor, with high accuracy (0.5S class for voltage/current, 1 class for power).

Identifies, stores, queries and deletes various trip types (overload, overvoltage, phase loss, etc.), with fault cause and time recorded for quick troubleshooting.

Supports four remote functions: telemetry, remote signaling, remote control, and remote adjustment, with automatic recognition of DL/T645 and Modbus protocols.

Three-phase active power accumulation, forward/reverse energy measurement, and multi-period freezing (minute/hour/day/month) for comprehensive energy management.

Measures 2nd to 21st harmonics, analyzes odd/even harmonic ratios, and supports voltage compliance statistics for power quality monitoring.

Supports online remote upgrades, optional terminal temperature monitoring, and data encryption for easy maintenance and secure operation.
