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...

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...
