JCB3LM-80 Elcb Breaker Provides Comprehensive Electrical Fault Protection

The JCB3LM-80 Elcb Breaker series delivers essential triple-protection against electrical hazards in residential and commercial installations. Combining earth leakage (RCD), overload, and short-circuit protection in a single device, these Earth Leakage Circuit Breakers (ELCB) safeguard lives and property by instantly disconnecting circuits upon fault detection. Engineered to IEC61009-1 standards, they ensure reliable operation across diverse electrical environments, providing critical safety assurance for homeowners and businesses alike. Their core function centers on monitoring current imbalance and triggering disconnection within milliseconds when deviations exceed safe thresholds.  

Technical specifications demonstrate exceptional versatility, with current ratings spanning 6A to 80A across 12 standardized settings. The series offers configurable tripping sensitivity with five residual operating current options (30mA, 50mA, 75mA, 100mA, 300mA), allowing precise adaptation to specific circuit protection requirements. All variants feature a robust 6kA breaking capacity, effectively containing high-magnitude short-circuit currents. Multiple pole configurations ， including 1P+N, 2P, 3P, 3P+N, and 4P ， ensure compatibility with single-phase and three-phase systems up to 400V AC installations.  

Advanced fault discrimination defines this Elcb Breaker series, utilizing electromagnetic-tripping technology for overload/short-circuit protection alongside electronic amplification for sensitive residual current detection. The dual-mechanism design ensures Type A and Type AC variants accurately identify pulsating DC and alternating fault currents common in modern environments with electronic devices. Integrated thermal-magnetic trip units provide time-delay characteristics for overloads while maintaining instantaneous response to dangerous short-circuits, achieving optimal balance between safety and operational continuity.  

Installation flexibility is enhanced through standardized DIN-rail mounting and front-terminal accessibility. Visual indicators provide immediate status recognition: green for operational readiness, red for tripped conditions. The test button facilitates monthly safety verification without load disconnection. Environmental resilience includes operation from -25°C to +55°C with 85% relative humidity tolerance, while corrosion-resistant silver-alloy contacts ensure consistent performance throughout the device’s extended service life.  

The JCB3LM-80 Elcb Breaker series establishes fundamental electrical safety infrastructure for modern buildings. By integrating three critical protection functions with configurable sensitivity and universal compatibility, it delivers uncompromising defense against electric shock, fire risks, and equipment damage. For specifiers seeking IEC-certified protection solutions, this comprehensive product range represents the frontline defense in electrical distribution safety management.
