RCCB
Inquire NowDescription
The RCCB (Residual Current Circuit Breaker) is an essential safety device designed to protect against earth fault and leakage currents while providing isolation functionality. With its high breaking current withstand capacity, this device is highly reliable in preventing electrical hazards. It is compatible with terminal and pin/fork type busbar connections, ensuring versatile installation options. The RCCB features fire-resistant plastic components that can endure abnormal heating and strong impacts, making it ideal for various applications. When an earth fault or leakage current exceeds the rated sensitivity, the RCCB automatically disconnects the circuit, offering peace of mind against electrical shocks. Additionally, it operates independently of power supply and line voltage, free from external interference and voltage fluctuations.
