Medium Voltage Circuit Breakers Support Wind Applications

Eaton Corp. has launched the VCP-Wind medium voltage vacuum circuit breaker that is designed specifically for wind applications. The new, compact circuit breaker is engineered to provide reliable and robust circuit protection for wind farm collector substations.

The VCP-Wind circuit breaker incorporates Eaton's vacuum interrupting technology. Eaton's vacuum interrupters avoid the use of Sulfur Hexafluoride (SF6), which poses environmental and safety concerns. They are designed to reliably switch high stress currents, and require no cooling or ventilation systems. Additionally, they are encapsulated in epoxy resin material and are designed to require virtually no maintenance over the product life cycle.

Eaton's new 38 kV VCP-Wind breakers offer current ratings up to 2000 amperes (A) without fan cooling and 31.5 kiloamperes (kA). They meet American National Standards Institute (ANSI) and Institute of Electrical and Electronics Engineers (IEEE) C37.09 standards.
