Centre-break (CBD)

Products > Disconnectors

The centre-break disconnector consists of two arms which, by moving in a coordinated way on a plane which is perpendicular to that of the insulators supporting them, close the circuit at a point which is located approximately mid-way.

This is the most commonly used type of disconnector in the world, thanks to the simplicity of its design, which makes it particularly cheap. Its movement, however, requires a bigger phase-to-phase spacing compared to that required for other disconnectors with the same rated voltage.

Rated voltage: 36 - 550 kV

Rated continuous current: up to 6300 A

Rated short-time withstand current: up to 63 kA (3 s)
