The HNB9L-63 Series Residual Current Circuit Breaker (RCCB) is a high-performance protective device engineered for AC 50Hz power distribution systems, offering reliable leakage, overload, and short-circuit protection.
The HNB9L-63 1P+N Residual Current Operated Circuit Breaker (RCCB) is a high-precision electronic-type RCBO designed to provide dual protection against residual current (leakage) and overcurrent (overload and short circuit) in AC 50Hz electrical distribution systems.
The HNB9L-63 1P+N RCCB offers cost-effective protection for modern power networks—ideal for distribution systems where safety, performance, and compact size are essential.
With a rated voltage of AC 230V and current rating up to 63A, it offers reliable safety for a wide range of residential, commercial, and industrial applications.
This RCCB features a 1P+N configuration, ideal for single-phase two-wire systems, ensuring the live and neutral lines are simultaneously disconnected in the event of a fault. When a leakage current exceeds the set threshold or a person encounters an electric shock, the circuit breaker will instantly disconnect power to prevent serious injury or damage.
The HNB9L-63 series stands out for its compact design, advanced internal structure, and casing made from flame-retardant, high-impact-resistant materials, offering long-term durability and stable operation even in demanding environments.
