Fuji Electric 3P3E 100 AF Switch Surface Type Earth Leakage Circuit Breaker, DG103ND

The Fuji Electric Earth Leakage Circuit Breaker (ELCB) is a critical component in electrical systems, designed to protect against electric shock and fires caused by earth faults or leakages. Here are some key features and benefits:

• Ground Fault Protection: The ELCB detects earth faults by monitoring the imbalance between the live and neutral conductors. When it detects a ground fault, it quickly interrupts the circuit, preventing electric shock hazards.
• Human Safety: By promptly disconnecting power in the event of a ground fault, the ELCB helps protect individuals from electric shock, making it an essential safety device in residential, commercial, and industrial settings.
• Fire Prevention: Earth faults can lead to overheating and fires in electrical installations. The ELCB helps mitigate this risk by disconnecting power when it detects abnormal leakage currents, minimizing the potential for fire hazards.
• Sensitive Detection: Equipped with sensitive detection mechanisms, the ELCB can detect even small leakage currents, ensuring reliable protection against electric shock and fire hazards.
• Selective Tripping: Some models feature selective tripping capabilities, allowing the ELCB to isolate the faulty circuit while maintaining power to unaffected circuits, minimizing disruptions and downtime.
• Adjustable Sensitivity: Certain ELCB models offer adjustable sensitivity settings, enabling users to customize the device's response to leakage currents based on the specific requirements of the electrical installation.
• Compact Design: Designed to fit within standard electrical panels and enclosures, the ELCB features a compact and space-saving design, facilitating easy installation and integration into existing electrical systems.
