The Siemens Digital Monitoring Relay provides Advanced motor load oversight through integrated Bluetooth connectivity for wireless parameterisation. This 3UG5 series device effectively monitors voltage and power factors to protect against mechanical failures like pump idling or soiled filters by identifying precise limit deviations across industrial power networks.
Monitors networks up to 690 V
Supports current limits to 15 A
Wide supply from 24 to 240 V
Wireless parameter setting via Bluetooth
