The ABB 1SDA066882R1 is a 200 A, 4-pole molded case switch-disconnector from the MCS T3D PV series, rated for IEC 1100 V DC applications and carrying the F FCCU designation. This is a DC-rated device built for photovoltaic and other high-voltage DC isolation duties — the 1100 V DC rating puts it squarely in large-string solar combiner boxes or utility-scale inverter DC disconnects where a standard AC breaker won't hold off the arc.
Lifecycle stage is listed as current, meaning this order code remains in ABB's active catalog and is not subject to a phase-out or last-time-buy notice.
