- Description
Rated 200 A at 1000 V DC, the ABB 1SCA125626R1001 OTDC200E11 is a two-pole DC switch-disconnector on the S1.0 frame for base-mounted installation ahead of a photovoltaic inverter or combiner box. It isolates a single DC circuit, holds a 1500 V rated insulation voltage and a 12 kV impulse withstand voltage, and makes against a 10 kA short-circuit (Icm).

Selection Notes
At 200 A, per-pole power loss climbs to 6 W (12 W total), still inside the same S1.0 envelope used by the 100 and 160 A siblings, so no enclosure resizing is needed when scaling up within this bracket. Use this variant where string or sub-array current sits between 160 A and 200 A; above that, move to the 250 A unit rather than running this switch near its thermal limit. As with the rest of the E-series, the operating handle and shaft ship separately.
