Distribution Box Model Number

Distribution box model numbers identify specific types, sizes, and configurations of electrical distribution boxes, often reflecting the number of ways, material, and mounting type.

Understanding Model Numbers

Distribution box model numbers are manufacturer-specific codes that convey key information about the box, including:

• Number of ways or slots: Indicates how many circuits or connections the box can accommodate, e.g., 1-way to 36-ways .
• Material and construction: Plastic, polycarbonate, ABS, or metal enclosures, sometimes with IP65/IP67 protection for dust and water resistance .
• Mounting type: Surface-mounted, wall-mounted, or DIN rail compatible .
• Special features: Modular design, integrated LEDs, plug connections, or tamper-proof latches .

Examples of Model Numbers

• TOP Series (TOP-TS, TOP-TF, TOP-LS, TOP-PS, TOP-PF, TOP-S): These models range from 1-way to 36-ways, with dimensions and mounting sizes specified in manufacturer catalogues .
• AK-NW-40: A plastic distribution box for electronic PCB design, measuring 168x51mm, weighing 155g, and suitable for indoor/outdoor use .
• Murrelektronik M8 Series: Model numbers like 8000-84010-... or 8000-84110-... indicate connector type, cable type, and cable length, with modular components for flexible installation .
• EJB Series: Designed for hazardous environments, with options for portholes or windows to display instruments, and IP66/67 polycarbonate construction .

Tips for Identifying the Right Model

1. Check the number of ways required for your installation.
2. Verify the IP rating for environmental protection.
3. Confirm mounting compatibility (surface, wall, or DIN rail).
4. Consider modularity and expandability if future upgrades are expected.
5. Refer to manufacturer catalogues for exact dimensions and part numbers .

By understanding the structure of distribution box model numbers, you can select the appropriate box for your electrical installation, ensuring compatibility, safety, and ease of maintenance.
