English Introduction
CDM3L-125F/3300 80A 1/3/5 Time Delay 2 Moulded Case Earth Leakage Circuit Breaker
This product is a multi-functional protection device designed for low-voltage distribution systems, suitable for circuits with AC 50Hz and rated operational voltage up to 400V. It integrates earth leakage detection, overload protection, and short-circuit protection, significantly enhancing electrical safety and system reliability. Featuring a modular structure, the breaker combines installation flexibility with easy maintenance, catering to diverse applications in industrial, commercial, and residential scenarios.
Core Features & Advantages
-
Precise Earth Leakage Protection
Equipped with a high-sensitivity current transformer, the breaker continuously monitors leakage current. Upon detecting leakage exceeding preset thresholds, it trips within milliseconds to isolate faulty circuits, mitigating electric shock hazards and equipment damage.
-
Multi-Stage Protection Logic
Incorporates overload long-time delay and short-circuit instantaneous protection. The three-stage tripping characteristic (1/3/5 Time Delay 2) allows adaptive configuration for varied load profiles, balancing operational accuracy with noise immunity to minimize nuisance tripping.
-
Robust & Compact Construction
The housing utilizes high-strength engineering plastics with flame-retardant additives, ensuring mechanical durability and electrical insulation. An optimized arc-extinguishing system enhances breaking capacity while reducing contact erosion for extended service life.
-
User-Centric Operation
Features a status indicator window, leakage reset button, and test button for intuitive operation and troubleshooting. The ergonomically designed handle reduces operational fatigue during frequent use.
Typical Applications
- Main switch or branch circuit protection in industrial power distribution cabinets
- Low-voltage systems in commercial complexes, hospitals, and educational facilities
- Residential building main supply lines or dedicated circuits for high-power appliances
