RCCB
Inquire NowDescription
The RCCB (Residual Current Circuit Breaker) is an essential device designed to provide protection against earth faults and leakage currents, ensuring safety and functionality within electrical installations. Its high breaking current withstand capacity allows it to handle significant electrical surges, making it suitable for both residential and commercial applications. The RCCB is compatible with terminal and pin/fork type busbar connections, providing versatility in installation. Constructed with fire-resistant plastic components, it withstands abnormal heating and strong impacts, ensuring durability and reliability. With its automatic disconnection feature, the device promptly disconnects the circuit when an earth fault or leakage current exceeds the rated sensitivity, offering peace of mind against electrical hazards. It operates independently of power supply and line voltage fluctuations, ensuring consistent performance free from external interferences.
