HNB9L-63 3P+N Residual Current Circuit Breaker
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 Residual Current Circuit Breaker (RCCB) provides reliable protection, compact size and cost-effective installation for any low-voltage power distribution system.
Designed in 3P+N configuration, with a rated working voltage of 240/400V AC and a rated current of up to 63A, it is ideal for protecting modern power infrastructure.
When electric shock occurs or leakage current exceeds the safety limit, this RCCB can quickly disconnect the fault circuit within milliseconds to protect human life and connected electrical equipment. It ensures optimal safety for residential and commercial power systems.
This circuit breaker is ideal for applications where space, performance and reliability are critical.
