2P 4P RCCB Residual Current Circuit Breaker

Application Scenarios

This series of RCCB residual current circuit breakers and matching MCB miniature circuit breakers are core safety protection components for low-voltage power distribution systems, widely used by electrical engineers, construction contractors, power distribution equipment distributors and foreign trade importers across global markets, especially in Africa, the Middle East, Southeast Asia and Europe. They are perfectly suitable for a full range of power distribution scenarios, including residential apartments, villas, rental housing, commercial office buildings, shopping malls, hotels, schools, hospitals, industrial workshops, municipal engineering and temporary construction sites. Whether for new building power distribution system construction, old circuit renovation, or safety upgrade of existing electrical systems, this series of circuit breakers can effectively prevent electric shock accidents caused by current leakage, and avoid fire hazards caused by circuit overload and short circuit, ensuring the safety of personnel and electrical equipment. The products adopt standard DIN rail mounting design, which can be perfectly matched with plastic distribution boxes, forming a complete set of power distribution solutions for engineering projects.

Core Product Features

1. Complete Specifications for Diverse Needs: The RCCB leakage circuit breaker provides 2 pole and 4 pole configurations, with rated current of 40A, 63A and 100A, and optional leakage tripping sensitivity of 30mA (for personal protection) and 300mA (for fire protection), which can fully meet the needs of single-phase and three-phase power distribution systems. The matching MCB miniature circuit breaker is available in 1P, 2P, 3P and 4P configurations, with rated current from 6A to 63A (C-type tripping curve), 4500A breaking capacity, suitable for branch circuit control and protection.
2. High-Precision & Reliable Protection Performance: The RCCB adopts a high-sensitivity electromagnetic tripping system, which can quickly trip within 0.1s when leakage current is detected, effectively cutting off the power supply to avoid electric shock accidents. It has built-in anti-surge and anti-interference circuits, which can resist voltage fluctuations and grid interference, avoiding misoperation caused by lightning or transient current, ensuring stable and reliable long-term operation. The MCB has excellent overload and short-circuit protection performance, with fast tripping speed, which can effectively protect the connected electrical equipment and circuits.
3. High-Quality Material & Safe Structure: The shell of the circuit breaker is made of high-strength flame-retardant PC engineering material, which has excellent impact resistance, high temperature resistance and aging resistance, will not deform or crack in harsh environments, and effectively prevents fire hazards. The internal conductive parts are made of high-purity copper with silver alloy contacts, which have good electrical conductivity, low contact resistance, anti-arc and anti-wear properties, ensuring a service life of more than 10,000 times of on-off operations. The products are designed with fully insulated structure, which can effectively avoid the risk of electric leakage and electric shock during installation and use.
4. Standard Compliance & Easy Installation: The products comply with BS 4293 and international CE standards, and are fully adapted to the grid environment and installation habits of global markets. They adopt standard 35mm DIN rail mounting design, which can be quickly installed and disassembled in various distribution boxes, greatly improving the efficiency of on-site installation and maintenance by electricians. The clear terminal marks and wiring structure make the wiring operation simple and standardized, reducing the probability of wiring errors.
