ABB 2CSF204568R3400 F204 B-40/0.3 4P 40A 300mA Type B Residual Current Circuit Breaker

The ABB F204 B-40/0.3 residual current circuit breaker (RCCB), catalog number F204 B-40/0.3 (SKU: 2CSF204568R3400), is a 4-pole, 40A, 300mA Type B device from the ABB F200 series designed to provide personnel and installation protection against earth leakage currents — including pulsating DC and smooth DC fault currents generated by modern frequency converters, EV chargers, and renewable energy systems. Its DIN-rail mount form factor fits standard industrial control panels, and its compact 70 × 85 × 69 mm footprint ensures efficient panel space utilisation.
