LMBF 63A 2P Intelligent Flooding Anti-Shock Smart Circuit Breaker

Product Overview

The LMBF series intelligent flooding anti-shock circuit breaker is an all-in-one electrical safety protection device for single-phase terminal distribution systems. It integrates eight core protection functions – overload, short-circuit, earth leakage, overvoltage, undervoltage, lightning surge, over-temperature self-check and water immersion anti-shock – into one compact DIN-rail module, replacing the combination of multiple separate protection devices and greatly improving system reliability.

Optimized for water immersion and electric shock scenarios, it adopts high-sensitivity residual current detection with millisecond-level fast tripping, which cuts off power rapidly when dangerous leakage occurs under water flooding conditions, effectively limiting contact voltage within a safe range and preventing fatal electric shock accidents. The built-in LED digital display shows real-time parameters and fault status, and all protection thresholds can be set via front panel buttons to adapt to different scenarios and load requirements. It is widely installed in residential main distribution, bathroom and kitchen wet areas, outdoor socket circuits, commercial premises and temporary construction sites, providing all-round protection for personal safety and electrical property.

Key Product Features

✅ 8-in-1 Comprehensive Protection System Integrates overload protection, short-circuit protection, earth leakage protection, overvoltage protection, undervoltage alarm, lightning surge protection, over-temperature self-check and water immersion anti-shock function. One device covers all major electrical hazards, eliminates the need for multiple separate components and saves cabinet space.

✅ Millisecond-Level Flooding Anti-Shock Action High-sensitivity residual current detection algorithm optimized for water immersion scenarios. Trips within milliseconds when dangerous earth leakage occurs under flooding or water contact conditions, reliably prevents electric shock accidents and provides personal safety protection for wet and water-exposed environments.

✅ LED Digital Display & Intuitive Control Clear LED digital display shows real-time voltage, current, leakage value and fault codes. Equipped with SET, up/down adjustment and OK buttons for intuitive parameter setting and fault query. Operators can view status and adjust thresholds directly on site without additional tools.

✅ Fully Adjustable Protection Parameters All key protection parameters including leakage current, overvoltage threshold and undervoltage threshold can be customized via the front panel. Flexible adaptation to different grid conditions, load characteristics and safety level requirements, from high-sensitivity personal protection to general distribution fire protection.

✅ Active Self-Check & Fault Warning Built-in over-temperature self-check function automatically monitors internal temperature and operating status. Undervoltage and fault alarm mechanism provides timely warning of abnormal grid conditions. Proactive fault identification reduces hidden dangers and improves system reliability.

✅ Standard DIN-Rail Modular Design Fits universal 35mm DIN rail for quick snap-on installation. Standard 2-pole modular dimensions, compatible with mainstream consumer units and distribution boxes. Easy for new installation, renovation upgrade and faulty device replacement.

✅ IEC Standard Compliance Designed and tested in accordance with IEC 61009-1 international standard for residual current operated circuit breakers. Passed breaking capacity test, tripping characteristic test, dielectric test and endurance test, qualified for global residential and commercial electrical safety projects.
