LTHH Line contactors are the perfect solution for application in 4kV systems, applied to both on board and fixed installations in rail applications.

Our product line provides a wide current range and high reliability. Thanks to the thin design and the single-side layout of power terminals, we reduce the device size and ensure easier operations.

Thanks to our yearlong experience, we can offer many configurations to cover all customer needs.
