Select Vertiv™ Geist™ rack PDU models support Residual Current Metering Type B (RCM-B). RCM-B continuously monitors the fault current of the power distribution within the IT rack. Customizable alarms provide immediate notifications of changes in residual current leakage allowing users to respond to a fault condition immediately to avoid potential catastrophic events such as critical equipment shutdown, electric shock, and electrical fires.
Application Brief BrochureRCM-B monitoring provides increased data center availability and reduces the time required to confirm compliance with local requirements.
- Vertiv™ rack PDU residual current metering is compliant with the EN62020 standard for total residual current metering of both AC and DC current
- RCM-B monitoring at the rPDU level provides permanent continuous residual current metering complying with DGUV regulation 3 and does not require system disconnection for testing
- The rack PDUs monitor per phase on three-phase rPDUs supporting the data center standard EN50600
- Higher personal, operational and plant safety
- Increased profitability
- Increased fire protection
- Early detection of data loss and network failure
- Fault current detection directly at the consumer socket for fastest possible fault localization
- Preventive safety to protect people from hazards caused by electric current
- Malfunctions and unexpected interruptions of operation of sensitive equipment are minimized
- Insulation faults in newly installed systems and devices are detected immediately
- Permanent plant and equipment monitoring
- Continuous monitoring equipment reduces the effort of repeat tests
- According to the DGUV accident prevention regulation 3, the test intervals for insulation measurement can be adapted to practical requirements by means of permanent residual current monitoring
- No expensive and unplanned plant shutdowns and service calls
- Flammable residual currents are already detected in the formation phase
