Product Features

Features

1. Ultra-High Short-Circuit Breaking Capacity
Advanced arc control technology achieves higher interruption capacity compared to industry standards, ensuring reliable protection for industrial-grade electrical systems under extreme fault conditions.

2. Dual-Mode Connection Interface
Integrated hybrid terminal design supports both rigid busbar docking and flexible cable clamping, enabling tool-free adaptation to diverse installation scenarios while reducing wiring time by 40%.

3. Energy-Storage Mechanism for Longevity
Spring-assisted operating system with 10,000 mechanical cycles endurance , featuring wear-compensation technology

4. Advanced Composite Enclosure
with with fame-retarcant,heat-resistant, and impulse -proof properties integrated arc-quenching chambers for contained fault events.

5. Dynamic Current-Limiting Topology
Intelligent let-through energy suppression reduces peak fault currents by 65-80%, enabling downstream device specification optimization with 30% overall system cost reduction potential.
