What are the specifications for an IP65 distribution box

An IP65 distribution box is a dustproof and waterproof enclosure designed for outdoor and industrial electrical installations, available in multiple sizes and materials with DIN rail compatibility. Protection RatingIP65 rating ensures complete protection against dust ingress (level 6) and protection against water jets from any direction (level 5), making it suitable for outdoor and harsh environments. Compliant with IEC 60529 standards for ingress protection.

Material and Construction

Common materials include ABS or polycarbonate (PC) plastics, which are halogen-free, UV-stabilized, and resistant to mechanical stress. Transparent windows are often made of tinted polycarbonate with UV protection for monitoring internal components without opening the box. Lightweight yet durable, suitable for wall-mounting or surface installation.

Size and Module Capacity

Available in 4-way to 54-way configurations, with options for single, double, or triple layers depending on the model.

Supports DI

N rail mounting (TH35x7. 5 mm) for modular breakers, relays, and terminals. Compact models (4–18 ways) are ideal for small residential or light commercial setups, while larger models (12–54 ways) suit industrial or photovoltaic applications.

Electrical and Environmental Features

Designed for low-voltage applications in compliance with directives such as 2014/35/EU.

Resistant to U

V exposure, rain, dust, and humidity, ensuring long-term reliability in outdoor installations. Flammability ratings of housing plastics are evaluated per UL 94 standards.

Applications

Widely used in photovoltaic systems, industrial plants, commercial buildings, and outdoor electrical distribution. Protects terminals, splices, and miniature modules from environmental hazards while maintaining safe and organized wiring.

Additional Features

Some models offer pre-assembled options with multiple rows of modules for easier installation. Reinforced bosses and extra clearance for structured cabling improve internal organization and safety. Customizable solutions are available for high-UV, high-temperature, or coastal environments.

In summary, an IP65 distribution box provides robust protection, versatile sizing, and reliable material construction for outdoor and industrial electrical applications, ensuring safe and durable power distribution.
