B Type Residual current circuit breaker RCCB
Inquire NowDescription
The B Type Residual Current Circuit Breaker (RCCB) is a crucial safety device designed to provide effective protection against earth faults and leakage currents, ensuring the safety and integrity of electrical systems. This innovative breaker features a high short-circuit current withstand capacity, making it reliable for various applications. Its versatility allows for terminal and pin/U type busbar connections, ensuring compatibility with different installation setups.
With an on/off display function that indicates the contact position, users can easily monitor the breaker’s status. Constructed with fire-resistant plastic parts, this RCCB is capable of enduring abnormal heating and strong impacts, enhancing its durability. Importantly, it automatically disconnects the circuit when an earth fault or leakage current exceeding the rated sensitivity occurs, providing an added layer of safety.
