1SYF202015R1630

The ABB 1SYF202015R1630 (FB202 AC-63/0.03) is a 2-pole Residual Current Circuit Breaker (RCCB) from the FB200 series, designed to safeguard people and electrical installations against earth fault currents. It provides crucial protection against electric shock by indirect contact, additional protection against direct contact thanks to its $30text{ mA}$ high-sensitivity trip threshold, and defends against fire hazards caused by insulation faults. Built in strict compliance with IEC 61008 / IS 12640-1 standards, it is widely utilized across higher-load residential, commercial, and light-industrial power distribution setups.
