2. Decentralized devices: Centralized control of decentralized equipment like local air conditioning in buildings, elevator sub-control modules, and zoned lighting in shopping malls;

3. Outdoor/temporary scenarios: Temporary power distribution at construction sites, control of agricultural irrigation equipment, with easy mobility and on-site installation;

4. Automation supporting systems: Control units for single-unit equipment (e.g., packaging machines, printing machines), directly interlocking with the main machine.

IP Rating:

IP30/IP40/IP55/IP66/IP67 etc.

Suggestion:

• Layout based on component traits (e.g., separate high-power and precision parts to avoid interference).

• Match IP rating to environment (IP54+ for dusty areas, IP65 for wet/outdoor use) and follow safety standards.

• Optimize heat dissipation (natural cooling for ≤5kW; fans/AC for ≥10kW) and wiring (separate strong/weak current).

• Reserve 10-20% space for future expansion; balance cost with practicality (prioritize standard sizes where possible).
