Rated voltage
Common voltage levels: 220V (single phase), 380V (three-phase four-wire).
Adaptable voltage fluctuation range: ±10%.
Rated current
Main switch current: usually 63A~400A (depending on load requirements).
Branch circuit current: 6A~32A (controlled by miniature circuit breaker).
Number of circuits
Standard configuration: 4~24 circuits (expandable according to requirements).
Each circuit is independently controlled (circuit breaker + contactor or intelligent module).
Protection level
Indoor cabinet: IP30~IP42 (dustproof and slightly splashproof).
Outdoor cabinet: IP54~IP65 (dustproof and waterproof).
Cabinet dimensions
Common dimensions (width × depth × height):
Small lighting box: 300mm × 200mm × 500mm (wall-mounted).
Large lighting cabinet: 600mm × 800mm × 2000mm (floor-mounted).
Installation method
Wall-mounted (exposed or concealed), floor-mounted (with base).
Applicable environment
Temperature range: -5℃~+40℃ (indoor), -25℃~+55℃ (outdoor).
Humidity: ≤90% (no condensation).

Functional characteristics
Branch control: independent switch for each circuit (manual or automatic).
Timing control: integrated time relay or intelligent controller (supports time control, light control).
Remote monitoring: optional PLC or IoT module (remote control via mobile phone/computer).
Emergency lighting switching: equipped with ATS automatic switching device (switch to UPS or generator when the mains power is off).
Structural characteristics
Modular design: modular installation of circuit breakers, contactors, instruments, etc. for easy maintenance.
Material:
Indoor: cold-rolled steel plate sprayed or engineering plastics.
Outdoor: stainless steel or galvanized steel plate (anti-corrosion).
Heat dissipation design: vents or fans (forced heat dissipation is required for high current cabinets).
Safety characteristics
Overload and short circuit protection: each circuit is equipped with a miniature circuit breaker (MCB) or fuse.
Leakage protection: optional residual current circuit breaker (RCD).
Lightning protection: outdoor cabinets need to be equipped with surge protectors (SPD).
Compliance with standards: GB 7251.3 (special standard for low-voltage lighting distribution boxes).
Scalability
Intelligent lighting control systems (such as DALI, KNX) can be integrated.
Supports power metering function (installation of electric meters).
