Usage scenario of WLM7DC solar mccb

WLM7DC patented technology & design innovation

1. Large opening distance

2. Large capacity metal anti-dissociation grid

3. Narrow slit pressurized air blowing solution

4、Enhanced Coordination and Selectivity

Coordination and selectivity are critical aspects of electrical protection, especially in complex DC systems where multiple MCCBs may be installed in series. DC MCCBs are designed to offer enhanced coordination and selectivity features, ensuring that in the event of a fault, only the MCCB closest to the fault location trips, minimizing the impact on the rest of the system.

This selective coordination is essential for maintaining continuity of power to unaffected areas of the DC system, preventing unnecessary shutdowns and disruptions. Additionally, the ability to coordinate multiple MCCBs ensures that the protection scheme is optimized for the specific characteristics of the DC installation, providing a tailored and reliable protection solution
