The HNB1L-63 1P+N Residual Current Circuit Breaker (RCCB) is an electronic-type protective device specifically engineered for single-phase two-wire systems (1P+N) operating at AC 230V/400V, 50Hz.
It supports rated currents up to 63A, and delivers a short-circuit breaking capacity of 6kA, ensuring reliable residual current, overload, and short-circuit protection for both residential and commercial applications.
The HNB1L-63 1P+N RCCB is an ideal component for modern electrical safety infrastructure. This RCCB delivers a reliable safety solution with high-precision electronic detection and robust design.
This RCCB is designed to quickly disconnect the power supply when a leakage current or electric shock risk is detected, thereby protecting human life and connected equipment. Its electronic sensing technology ensures precise and timely response to ground faults and overcurrent events.
The 1P+N configuration ensures optimal protection for line and neutral conductors in low-voltage installations, making this circuit breaker a preferred solution for small office buildings, apartments, homes, and light industrial environments.
