RESIDUAL CURRENT CIRCUIT BREAKER
Inquire NowDescription
The Residual Current Circuit Breaker (RCCB) is a vital electrical component designed to enhance safety in electrical installations. With its elegant, arc-shaped cover and handle, this device ensures comfortable operation while maintaining an appealing aesthetic. The RCCB comes equipped with a contact position indicating window and a transparent cover for easy labeling, making it user-friendly and practical.
In case of an overload in the protected circuit, the RCCB handle trips and remains in a central position, allowing for quick resolution of any faults. This feature prevents manual operation from obstructing the safety mechanism. The RCCB offers exceptional protection against earth fault leakage current and serves as a reliable function of isolation.
Constructed from fire-resistant plastic, this device withstands high short-circuit current and is designed to endure abnormal heating and strong impacts. It automatically disconnects the circuit when an earth fault leakage current exceeds the rated sensitivity, and operates independently of power supply and line voltage, free from external interference.
