ABB OTDC315FV02 2-pole DC switch disconnector rated at 315 A and 1500 V DC for utility-scale photovoltaic systems and industrial DC isolation.
The ABB 1SCA158176R1001, also known as the OTDC315FV02, is a fully optimised 2-pole DC switch disconnector designed specifically for utility-scale photovoltaic power plants and other demanding high-voltage DC applications. Rated at 315 A with a maximum operating voltage of 1500 V DC, it delivers dependable switching and safe isolation for modern renewable energy systems.
The compact OTDC315FV02 helps manufacturers reduce the size of combiner boxes and inverter enclosures whilst improving system efficiency. Compared with conventional designs, the optimised two-pole construction reduces switch losses by up to 35% and occupies up to 30% less installation space.
Designed for front operation with the mechanism positioned at the end of the switch, the OTDC315FV02 is supplied with mandatory phase barriers for enhanced safety. Compatible operating handles, shafts and bolt kits are available separately, allowing flexible integration into a wide range of industrial and photovoltaic installations.
As photovoltaic systems continue to move towards 1500 V DC architectures, high-performance switching equipment plays an increasingly important role in improving efficiency and reducing installation costs. Compact disconnectors help manufacturers build smaller combiner boxes and inverter systems without compromising safety or performance.
The ABB OTDC315FV02 combines high current capacity, compact dimensions and dependable electrical isolation, making it an ideal choice for modern utility-scale renewable energy projects.
