ETL1-63 Residual Current Circuit Breaker (RCCB) offers reliable protection against electrical leakage currents, significantly reducing the risk of electric shock caused by indirect contact. Designed for versatility, it supports both single-phase (240V, 1P+N) and three-phase (415V, 3P+N) power systems, with a rated current capacity of up to 63A. This ensures dependable performance for a wide range of applications in residential, commercial, and industrial environments.
