Reliable in extreme conditions Easy installationEnergy efficiency Designed for harsh environments Solar farms are typically located in remote and inhospitable environments. The OTDC switch-disconnectors are designed to offer efficient and reliable performance even in high ambient temperatures and harsh environmental conditions. They are virtually maintenance-free. The unique contact design results in a lower temperature rise, making only a minimal contribution to the overall heat-rise within any enclosure. The patented dual magnetic breaking (DMB) solution in our larger OTDC 100...1600...

Switch-disconnectors OTDC and OTDCP Typical photovoltaic applications 1 Direct current switch-disconnectors by ABB offer reliable switching for a wide range of photovoltaic (PV) applications. They are durable and virtually maintenance-free, and offer easy installation for all imaginable situations. | 1SCC301021C0201 | Switches for photovoltaic applications Depending on the solar farm layout and the customer’s wishes, the OTDC switch-disconnectors may be used in one or more sections of the overall setup, on the DC side prior to the inverter. The most typical uses for direct current...

Inverter DC-side String combiner box The switch-disconnectors can also be used to disconnect individual arrays. In larger photovoltaic (PV) sources arrays, which consist of parallel-connected strings, are often used, with combiner boxes grouping individual strings together. Combiner boxes are an ideal place for placing PV devices, for example control and over-current protective devices. Switches inside combiner boxes allow possible fuse replacement and safe maintenance to be performed on individual arrays. Recombiner box Additional disconnect switches may also be installed in the proximity...
