Co Box Manufacturers In Madhya Pradesh
An outdoor electrical connection is only as reliable as the box protecting it. One failed seal during a monsoon and one cracked housing under summer heat and you're looking at tripped circuits, corroded terminals, and a maintenance crew on-site.
Since 2009, NR Enterprises has manufactured CO Boxes specifically built for Madhya Pradesh's outdoor conditions. As trusted CO Box manufacturers in Madhya Pradesh, we build every enclosure with IP65 and IP66 ratings, UV-stabilized housings, and stainless steel hardware, protecting over 10,000 installations across highways, smart cities, telecom networks, and industrial sites without a single reported water ingress failure in 16 years.
What is a CO Box?
A CO Box (Central Office Box) is a weatherproof enclosure that houses and protects outdoor electrical terminations. Wherever a power cable enters a pole, a telecom cable branches at a distribution point, or a control wire connects to a field device, CO Box keeps that connection sealed, secure, and accessible only to authorized personnel.
Detailed Description
Key features
- Our CO-6 and CO-8 models carry IP66 certification, suitable for direct monsoon exposure and C4 coastal corrosion environments.
- PVC models resist UV degradation for 10+ years without cracking; MS powder-coated models are used where mechanical strength is required, such as highway junctions and industrial yards.
- Cable entries of 20mm, 25mm, and 32mm are available on all four sides, pre-drilled with double compression gland fittings. Cables can enter the box from any side without any site preparation.
- Terminal blocks from 6 to 16 sq mm are installed ready to use, and all boxes have a padlock hasp for protection on public utility infrastructure installations.
- All housing bodies are fire-retardant rated V0 according to UL94 standards.

Where CO Boxes are used
- Street light and CCTV poles: The CO-4 (200×200 mm) is the standard for street light pole power feeds, fitting NHAI and PWD specifications directly. For CCTV poles carrying both power and data cables, the CO-6 provides 12 terminals and six 32mm entries across all sides.
- Telecom and FTTH distribution: The CO-4 and CO-6 are frequently used for pole-mounted FTTH branch points, which must be accessible for frequent inspection and maintenance while remaining completely sealed.
- Solar power generation and industrial installations: Solar CO-3 and CO-4 versions are commonly found at rooftop and ground-based solar energy farms in Rajasthan, Gujarat, and Maharashtra. Industrial CO-6 and CO-8 MS body models are typically used for electric motors, pumps, and sensors wiring within industrial compounds.
NR Enterprises supplies to NHAI highway contractors, PWD project teams, telecom installers, and industrial clients as established CO Box suppliers in Madhya Pradesh with ready stock across all four models for immediate dispatch. For project teams and procurement managers looking for certified CO Box suppliers in Madhya Pradesh, our IP65/IP66 test certificates and NHAI approval documentation are available with every order.
