WLM7DC-400A-2300 2Poles WLM7DC Series Photovoltaic solar type dc mccb 250vdc/500vdc/750VDC/1000VDC/1500VDC 250A 3 Poles solar mccb
MCCB Highlights
WLM7DC MCCB: Application field of centralized inverter: PV string is output to DC combiner box for confluence, and then DC/AC inverter is used for inversion. After AC output, the voltage is boosted and connected to the grid. DC combiner box and DC side of inverter shall be equipped with DC circuit breaker, with working voltage of DC1000V → DC1500V.
Remote Monitoring and Communication Capabilities
In the era of smart and connected systems, the ability to remotely monitor and communicate with electrical components is becoming increasingly important. DC MCCBs are equipped with advanced communication capabilities, allowing for remote monitoring of their status, trip events, and operational parameters. This level of connectivity enables proactive maintenance and troubleshooting, leading to improved system reliability and reduced downtime.
Furthermore, remote communication capabilities also facilitate integration with supervisory control and data acquisition (SCADA) systems, allowing for centralized monitoring and control of DC MCCBs across multiple locations. This level of integration enhances the overall visibility and management of the electrical infrastructure, contributing to improved operational efficiency and maintenance practices.
