The HNB1L-63 Residual Current Circuit Breaker (RCCB) is a high-performance electromagnetic-type breaker designed for three-phase four-wire systems (3P+N).
The HNB1L-63 RCCB combines a robust internal structure with compact external dimensions, and features a housing made of flame-retardant, high-impact-resistant material for enhanced durability in high-load applications.
Whether for residential infrastructure or industrial operations, the HNB1L-63 3P+N RCCB delivers high-efficiency fault protection with compact design and robust performance, making it an ideal breaker solution for modern electrical systems.
With a rated voltage of AC 240/400V, rated current up to 63A, and a breaking capacity of 6kA, this RCCB ensures reliable leakage, overload, and short-circuit protection in low-voltage distribution networks.
This model is specially engineered to instantly disconnect power when a leakage fault or electric shock occurs, effectively protecting people and sensitive electrical equipment from damage and danger. The 3P+N configuration enables full-phase and neutral line protection, making it ideal for demanding commercial and industrial environments.
