Product Description

The Mitsubishi NV125-CV is a molded-case leakage current breaker designed for advanced electrical protection in industrial and commercial distribution systems. It integrates earth leakage protection with standard circuit-breaker functions, safeguarding against ground faults, short circuits, and overloads. Suitable for three-phase networks up to 440V, this 3-pole breaker features a compact design with a 125A frame capacity and supports adjustable leakage current settings.

Standard Features

Compliant with CE/CCC standards, it ensures reliable operation in environments requiring stringent safety measures, such as manufacturing plants or power distribution panels. Its robust construction and modular accessories enhance adaptability across diverse applications.

  • Earth Leakage Protection:Detects ground faults and trips at configurable leakage currents,preventing electric shocks and fire hazards

  • Multi-Protection Integration:Combines leakage protection with thermal-magnetic tripping for overloads and short circuits, ensuring comprehensive circuit safety

  • Adjustable Current Ratings:Supports multiple trip-unit ratings (e.g., 63A, 80A, 100A, 125A) within a unified 125A frame, enabling flexible load matching

  • High Breaking Capacity:Offers a 10kA fault-current interruption capability, enhancing system resilience during severe electrical faults

  • Front-Terminal Wiring:Simplified front-connected terminals facilitate easy installation and maintenance

  • Certified Compliance:Meets CE and CCC standards for safety and performance reliability
