Residual current monitors

Residual current monitors

VARIMETER RCM - Reliably detect residual currents

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.
