ABB F202AC-40 is a two-pole residual-current circuit breaker (RCCB) in ABB’s F200 family that protects circuits from earth leakage by disconnecting on residual current. It is rated for 40 A (In) and is available in multiple residual-current sensitivity options, including F202AC-40/0.03 (30 mA), F202AC-40/0.1 (100 mA), and F202AC-40/0.3 (300 mA), all Type AC for alternating-current leakage detection. Typical applications include safeguarding two-pole circuits in residential, commercial, and light-industrial panel installations where reliable RCD protection is required.
