Outdoor Electrical Box with Cooling Fan 400x300x200mm IP65 Waterproof Metal Enclosure

Advanced Thermal Management with Active Cooling

This industrial-grade outdoor metal enclosure features an advanced dual-ventilation structure equipped with an integrated 12V active cooling fan (80x80mm). Rather than relying entirely on passive conduction, the system draws fresh air through a protected lower intake and expels hot air out of the dual side-mounted ventilation hoods. This continuous airflow layout prevents heat pockets and significantly lowers the operational temperature of high-performance components inside, such as EV chargers, solar inverters, and network switches.

Rugged Structural Engineering and Precision Dimensions

Engineered for reliable industrial performance, this heavy-duty enclosure measures exactly 400x300x200mm (15.75" x 11.81" x 7.87") and is forged from high-tensile 1.1mm thick cold-rolled steel plate. The cabinet is finished with an anti-corrosive, multi-layered industrial matte grey powder coating. This specialized treatment offers exceptional scratch resistance, impact buffering, and defense against UV degradation, salt spray, and extreme weather changes.

Optimized Internal Component Integration and Toolless Expansion

The interior layout is highly optimized for technical efficiency and clean wiring:

• Dual-Chamber Perforated Backplate: A heavy-gauge internal cold-rolled steel grid plate divides the internal area into versatile horizontal mounting tiers.

• Premium Aluminum DIN Rail: A pre-included 25mm wide aluminum DIN rail allows for instant, standardized mounting of circuit breakers, contactors, and industrial relays.

• Smart Knockout System: The bottom panel features dual pre-punched knockout holes, allowing installers to tap out entries cleanly without risking structural cracking or requiring heavy-duty metal drilling bits.

• Full Cable Gland Complement: Standard NPT 3/4" waterproof cable glands (M25x1.5) are included to lock incoming wires securely while maintaining total moisture-proofing.

Dual-Mode Mounting Flexibility and High Security

Whether deploying on industrial infrastructure or commercial properties, the structural back-plate supports versatile configurations:

• Wall Mount Mode: Secured flush against masonry or concrete using heavy-duty expansion sleeves through the pre-drilled integrated top and bottom structural flanges.

• Pole Mount Mode: Optimized for street poles, utilities, and traffic monitoring systems utilizing the included high-strength steel hose clamps.

• Anti-Vandalism Security: Features a robust central cam lock equipped with a weather-shielding lockable cover to prevent unauthorized physical tampering, water ingress, or internal damage in public environments.

Frequently Asked Questions (FAQ)

Q1: How does the active cooling fan maintain the IP65 waterproof rating during heavy downpours?

A: The dual ventilation openings on the right side of the enclosure are guarded by heavy-duty, downward-sloping steel louver hoods lined with fine anti-insect mesh filters. This mechanical design sheds heavy rain falling at severe vertical angles away from the vent ports, ensuring zero water ingress even while the 12V fan actively circulates internal air during a rainstorm.

Q2: Does the bottom panel require manual drilling to feed power cables through?

A: No, manual drilling is minimized. The bottom plate is engineered with two pre-configured structural knockout zones. Technicians can use a standard hammer or punch tool to pop open the clean entries cleanly without cracking the surrounding paint or steel. The package includes professional NPT 3/4" (M25x1.5) cable glands that seal perfectly into these entry points.

Q3: What mounting accessories are bundled inside the box, and can it be mounted to utility poles?

A: This enclosure features a universal dual-mounting configuration straight out of the box. The box comes fully prepared with pre-installed top and bottom heavy-duty steel wall-mounting flanges. Additionally, the kit includes adjustable steel hose clamps, allowing seamless pole-clamping installations on street lights, monitoring posts, or square pillars without requiring custom fabricated brackets.

Q4: What are the exact dimensions of the internal mounting surfaces and the included DIN rail?

A: The total outer shell envelope measures 400x300x200mm (15.75" x 11.81" x 7.87"). Inside, you are provided with a multi-slotted cold-rolled steel plate split by a center shelf layer. The bundled high-grade aluminum DIN rail measures 25mm (0.98") in width and is precision cut to span across the width of the back-plate, making it instantly ready for modular circuit breakers and PLC terminals.
