M3E Electronic Adjustable MCCB Molded-Case-Circuit-Breaker
JINGE M3E series is a high-performance electronic adjustable molded case circuit breaker, designed for precision power distribution and intelligent electrical systems. Adopting a high-precision electronic trip unit, it supports free adjustment of protection parameters to match various complex working conditions.
Compliant with IEC 60947-2 and GB 14048.2 standards, M3E operates at AC 400V/690V, covering rated current from 100A to 630A. It provides accurate overload, short-delay and instantaneous protection with high stability and strong anti-interference ability, making it an ideal choice for precision equipment, data centers, automated production lines and intelligent power distribution systems.
Key Adventages
- High-precision electronic trip unit: Delivers more accurate and stable protection than traditional thermal-magnetic types.
- Full adjustable protection parameters: Ir, Isd, Ii can be freely set to match different loads and working conditions.
- Wide voltage & current range: Suitable for 400V/690V grids, with frame current from 100A to 630A.
- High breaking performance: Up to 65kA ultimate breaking capacity to ensure reliable fault interruption.
- Strong anti-interference ability: Stable operation in industrial environments with vibration, noise and complex loads.
- Long service life & low failure rate: Optimized structure for long-term heavy-duty operation.
- Perfect for intelligent systems: Compatible with automated control and smart power distribution platforms.
