Downtime Reduced By New Communication
Interface
Moulded-case circuit breakers (MCCB) with advanced communications capabilities from Moeller are setting new benchmarks for power distribution and automation applications.
They enable scanning and the display of diagnostics and operating data, the detection of current values, parameter definition and remote control of the circuit-breakers on-site As part of Moeller's commitment towards increasing the intelligence of its devices, the new NZM1, 2, 3 and 4 MCCB range is able to store and communicate short-term operational history when used in conjunction with a data management interface (DMI)

Moeller makes energy saving easy
The new efergy wireless energy monitor from Moeller Electric makes it easy to reduce your carbon footprint in the home, office or small building.
Communications capabilities are standard across the board in all MCCBs incorporating electronic release.
The DMI is connected to the circuit breaker via a simple plug-in connection.
When used in power distribution boards and systems, the DMI gives users the ability to access and transfer operational data to a central control system using open fieldbus interfaces, such as Profibus DP.
Data managed in this way can include information relating to malfunctions, maintenance and diagnostics.
This increased transparency of the system will reduce response times to critical states, such as over current, phase imbalance or phase failure.
Such rapid intervention can help avoid system breakdowns and allows preventive maintenance to be planned - increasing machine availability and avoiding costly downtime.
