Unplanned interruptions of the operation of machines and systems are a significant cost factor. Insulation errors are a frequent cause for this. In grounded networks (TN networks), DOLD difference current sensors ensure reliable residual current monitoring. Expensive standstill time is avoided by this and, in addition, a possible risk of fire that latently exists by a gradual insulation error is also prevented. The difference current sensors are universally deployable as they can detect both direct and alternating current.

The residual current monitoring detects both alternating as well as direct current. This makes it universally usable and protects through the early notification of various dangers.
