  • Description

The ABB 1SCA158244R1001 OTDC630F11 is a two-pole DC switch-disconnector rated 630 A at 1000 V DC on the M frame, the top current step in this base-mounted family for utility-scale photovoltaic combiner boxes. It carries a 10 kA short-circuit making capacity (Icm) and a 1500 V rated insulation voltage.

Selection Notes

The 630 A headline figure is a DC-21B resistive rating only -- DC-22B mixed-load duty caps at 400 A and the DC-PV1/PV2 string ratings sit at 500 A, so a reverse-current PV string application should be sized against 500 A rather than 630 A. This is the largest current step in the M-frame OTDC family while keeping the same enclosure as the 400 and 500 A units, which simplifies combiner box layout. At 1000 V DC it suits installations capped at that bus voltage; a 1500 V string needs the equivalent higher-voltage variant.
