Smart MCCB integrating LV sensing, protection, communications and remote control for digital distribution networks
The Massivene remote-control Smart MCCB is designed for next-generation power systems and digital LV distribution. It combines circuit protection, electrical measurement, status sensing, data communications and remote control, upgrading the conventional LV switch to an intelligent end device with both sensing and control capability for fault protection, remote operation and digital O&M.
Provides three-stage overcurrent protection: long-time overload, short-time short-circuit and instantaneous short-circuit protection. Optional thermal-magnetic backup, phase-loss, neutral-loss, overvoltage, undervoltage and overtemperature protection improves circuit protection and upstream/downstream coordination.
Collects voltage, current, power, energy, temperature and breaker status data, and provides energy, load, outage and operating statistics for circuit monitoring, fault assessment and O&M analysis.
Monitors harmonics, three-phase unbalance, voltage fluctuation, voltage sag, interruption and swell, providing a more complete data foundation for LV distribution condition analysis.
Supports RS-485, HPLC and Bluetooth. RS-485 supports Modbus and DL/T 645 and works with smart gateways and upper-layer systems to upload operating data, status and alarms.
An electric operating mechanism executes remote open and close commands and returns breaker status, supporting remote operation and control of LV distribution circuits.
