Applications:

- Commercial Buildings: In malls, offices, and hotels, it ensures continuous fresh air supply and efficient stale air exhaust. Controls exhaust fans to maintain comfortable indoor air quality, particularly in high-traffic, high-pollution areas like kitchens, restrooms, and smoking zones.
- Industrial Facilities: Essential for factories (chemical production, food processing, high-dust/fume manufacturing). Automatically adjusts exhaust fan speed based on pollution levels, with built-in protection shielding electrical components from industrial hazards (overcurrent, short circuits, mechanical damage).
- Residential Buildings: Manages fresh air intake and exhaust in high-rises (individual apartments or common areas). Delivers fresh air to residents while protecting electrical equipment from typical household-level electrical faults and environmental factors.
- Educational Institutions: Supports large-scale ventilation needs in schools/universities (classrooms, libraries, gyms). Regulates fresh air exhaust fans to ensure proper circulation, safeguarding the electrical system against overloads during peak usage.

Technical Specifications:

Technical Parameter	Specifications & Descriptions
Rated Voltage	Common single-phase voltages: 110V, 220V; Three-phase voltages: 380V, 415V, etc. (depends on usage scenarios and power grid connection).
Rated Current	Small control cabinets: 10-30A; Large industrial cabinets: up to 100A or higher (mainly determined by the total power of controlled exhaust fans and other ancillary equipment).
Frequency	Generally 50Hz or 60Hz (consistent with the local power system frequency).
Short Circuit Withstand Current	Typically 10-50kA (determines the product’s ability to withstand current surges during short-circuit faults, protecting internal components and circuit safety).
