The digitally deep-integrated pole-mounted circuit breaker builds on electronic sensors and on-site digitization, further incorporating ceramic capacitor power harvesting to completely eliminate the risk of ferromagnetic resonance from traditional electromagnetic transformers. It offers higher integration, faster live-line installation, and significantly improves power supply reliability for users.

Key Features

Safety: Deep primary-secondary integration reduces auxiliary primary equipment and eliminates additional fault risks; mechanical interlocking eliminates remote misoperation hazards caused by automation

Effectiveness: Selective tripping for short-circuit faults (multi-level precise time-current coordination); selective automatic isolation of single-phase ground faults (transient-based fault location)

Advanced Technology: Built-in ECT/EVT; capacitor-based power harvesting solves terminal power supply challenges; protection rating up to IP67; total partial discharge ≤20pC

Intelligence: Terminal autonomously judges short-circuit or single-phase ground faults and issues tripping commands using machine learning and proprietary algorithms

User-friendly: Simple operation, no change to existing habits, no extra tools or procedures, no special training required; factory pre-commissioned; modular hot-swappable maintenance drastically reduces reliance on skilled technicians

Compact & Lightweight: Deep primary-secondary fusion (integrated ECT/EVT) reduces weight by more than 20kg, lowering installation difficulty and improving efficiency
