Eaton's 38 kV VCP-Wind compact vacuum circuit breakers use Eaton’s industry-leading vacuum interrupting technology. Eaton’s vacuum interrupters are free of SF6 gas, which poses environmental and safety concerns. Breakers are designed to reliably switch high stress currents, and require no cooling or ventilation systems. They are encapsulated in epoxy resin material and are designed to require virtually no maintenance. Ideal for wind farm collector substations.
