Distribution board OEM NT 24M IP40 350 – DIN rail enclosure for solar installations

Distribution board OEM NT 24M IP40 350 is a DIN-rail enclosure designed to organize and protect electrical components in solar panel systems and related installations. With space for up to 24 modules and an overall width of 350 mm, this indoor-mounted distribution board provides a compact, accessible location for circuit breakers, surge protection devices and terminal connections while maintaining IP40 protection against solid objects and limited access.

Advantages

The enclosure offers a standardized DIN-rail layout that simplifies installation and component replacement. Its 24-module capacity allows for flexible circuit distribution and expansion in photovoltaic arrays or auxiliary systems. The IP40 rating ensures basic protection for indoor environments, and the 350 mm width balances component density with ease of wiring and cooling. The unit's neutral aesthetic and modular interior make it suitable for neat, code-compliant electrical assemblies.

Suitable for

• Residential and commercial solar PV combiner or sub-distribution panels
• Indoor centralization of circuit breakers and surge protection devices
• Small to medium photovoltaic installations requiring organized DIN-rail mounting
• Control and monitoring junctions within renewable energy systems

Key specifications

• Installation type: DIN-rail mounted enclosure
• Module capacity: up to 24 modules (standard DIN module width)
• Protection rating: IP40 (protection against solid objects >1 mm)
• Width: 350 mm for compact component arrangement
• Intended mounting: indoor use on walls or inside technical rooms
• Material considerations: non-corrosive, electrically insulating housing (typical for distribution enclosures)

How to use

Install the distribution board on a suitable indoor wall or within a service cabinet following local electrical codes. Mount DIN-rail compatible devices such as miniature circuit breakers, surge protective devices and terminal blocks onto the internal DIN rails, observing correct spacing and manufacturer torque settings for connections. Route DC and AC wiring through the enclosure knockouts or entry points, separate photovoltaic DC circuits from AC circuits as required, and ensure proper earthing/grounding connections are implemented. After assembly, close the enclosure and verify the integrity of protective devices and wiring before energizing the system.

Usage recommendations

Use this distribution board in dry, ventilated indoor environments and follow local regulations for PV installations. Keep DC and AC wiring segregated, use suitably rated breakers and surge protection devices for photovoltaic systems, and ensure periodic inspection and torque checks of terminal connections to maintain safe operation.
