M6L-250M/4300A 125A 30/100/500MA 0S U Molded Case Leakage Protection Circuit Breaker
This product is a multi-functional circuit protection device designed for low-voltage power distribution systems, integrating overload protection, short-circuit protection, and leakage protection. It is suitable for industrial, commercial, and residential applications to enhance electrical safety management.
Key Features
- Adjustable Leakage Protection: Three leakage current settings (30mA, 100mA, 500mA) allow customization based on application requirements. The 30mA mode prioritizes human safety in sensitive environments, while the 500mA mode suits industrial equipment with higher fault tolerance.
- High Breaking Capacity: With a 4300A interrupting rating, it swiftly isolates fault currents during short circuits, minimizing potential equipment damage.
- Instantaneous Trip Response: Zero-time-delay tripping ensures immediate circuit interruption upon detecting leakage or short-circuit signals, reducing exposure to electrical hazards.
- Robust Load Capacity: Rated at 125A, it supports medium-to-high load distribution systems with stable performance under continuous operation.
- Compact Construction: High-strength housing provides mechanical durability and insulation integrity, enabling easy integration into diverse panel layouts.
Applications
- Main switch or branch circuit protection in distribution cabinets
- Lighting/power circuits in commercial buildings
- Residential main switches or dedicated lines for high-power appliances
- Temporary outdoor power supply systems
Technical Highlights
Enhanced arc-extinguishing mechanisms and contact materials improve interruption efficiency and service life. The bimetal-electromagnetic hybrid trip unit ensures precise overload response. Transparent status indicators and ergonomic handles facilitate visual operation monitoring and maintenance.
