4. Application Scenarios and Notes
- Compatible Components: Can be installed with household miniature circuit breakers (MCB), residual current circuit breakers (RCBO), PV convergence components, and other modular electrical devices (modular width: 18mm/module).
- Typical Applications: Outdoor lighting, balcony/bathroom power distribution, new energy vehicle charging piles, light industrial power distribution, marine/chemical auxiliary circuits.
- Usage Reminders: The box is only a protective enclosure; internal electrical components need to be separately matched to load power. For outdoor installation, it is recommended to use waterproof connectors for enhanced protection.
