STRATO is a system for switching operation with a great capability of electric insulation allowing a complete protection from overvoltage on the mains network.

STRATO could be activated by a storm detector (STORMDETEC), in automatic mode or by a local operator.
A locking input allows to forbid the opening of system contacts (e.g. : generating set not started).
