RCCB
Inquire NowDescription
The RCCB (Residual Current Circuit Breaker) is a vital safety device designed to provide protection against earth faults and leakage currents, ensuring isolation when necessary. Its high breaking current withstand capacity makes it suitable for various applications, offering enhanced safety and reliability. This device is compatible with terminal and pin/fork type busbar connections and features fire-resistant plastic parts that endure abnormal heating and strong impacts. Upon detection of an earth fault or leakage current that exceeds the rated sensitivity, the RCCB automatically disconnects the circuit, making it an essential component for electrical safety in any environment. It operates independently of power supply and line voltage, ensuring it remains unaffected by external interference and voltage fluctuations.
