Featuring a 6kA breaking capacity, this 3P+N RCCB offers comprehensive protection against residual current (leakage), overload, and short circuit events.
The HNB2L-63 3P+N Residual Current Circuit Breaker (RCCB) is a high-performance protective device designed for AC 50Hz three-phase four-wire power distribution systems, with a rated voltage of AC 230/400V and current capacity up to 63A.
Engineered for durability and safety, the HNB2L-63 3P+N RCCB is an essential component for modern three-phase electrical protection systems, offering dependable performance in a compact footprint.
When electrical leakage or personal electric shock occurs, the breaker is triggered to rapidly disconnect the faulty circuit, minimizing harm to personnel and equipment. The 3P+N configuration ensures full protection across three-phase lines and the neutral, making it ideal for commercial, residential, and light industrial applications requiring high reliability and safety.
