High Light MCB Circuit Breaker EnclosureOutdoor 4 Way Distribution Box36 Way DB Box Waterproof
4-36 Way Waterproof Distribution Box Outdoor MCB Circuit Breaker Enclosure
Product Overview

The 4-36 Way Waterproof Distribution Box is a professional-grade electrical solution engineered for high-density circuit management in demanding environments. This series provides a secure, IP65-rated housing for Miniature Circuit Breakers (MCB), Residual Current Devices (RCD), and Surge Protective Devices (SPD).

Available in multiple configurations from 4 to 36 modules, these enclosures are optimized for industrial automation, large-scale PV solar arrays, and commercial outdoor power distribution. The robust construction ensures long-term protection against environmental stressors while maintaining ease of access for maintenance.

Technical Highlights & Structural Advantages
High-Precision IP65 Weatherproofing

Utilizing a seamless polyurethane (PU) sealing strip and a reinforced screw-locking mechanism, this enclosure prevents water ingress even under heavy rain and low-pressure jets. The elevated internal design prevents internal condensation from affecting electrical terminals.

UV-Stabilized Polycarbonate Cover

The transparent PC cover allows for instantaneous visual inspection of circuit status without opening the enclosure. Unlike standard plastics, our PC material is UV-stabilized to prevent brittleness and yellowing in high-exposure environments (up to 70°C).

Impact & Chemical Resistance

The ABS body is engineered with thickened walls to achieve an IK08 impact rating. It provides excellent resistance against chemical corrosion, making it suitable for chemical plants, coastal projects, and heavy-duty construction sites.

Modular Scalability

The interior features adjustable DIN rail depth and ample wiring space (spacious wiring gutters). The 24 and 36-way models utilize a multi-tier layout to facilitate organized cable management for complex electrical systems.


Professional Applications
  • Solar Photovoltaic (PV) Systems: Used as a string combiner box to house DC breakers and surge protectors
  • Industrial Power Distribution: Centralized control for factory machinery and workshop lighting
  • Outdoor Infrastructure: Reliable protection for EV charging stations, telecommunication base stations, and street lighting controls
  • Commercial HVAC Systems: Housing for outdoor pump and motor controllers

Installation & Maintenance
  • Cable Entry: Pre-molded knockouts for various conduit sizes allow for flexible top or bottom entry
  • Wall Mounting: External mounting holes ensure the waterproof integrity of the internal chamber is never compromised during installation
  • Neutral & Earth Terminals: High-conductivity brass terminals included for stable grounding and neutral connections

Frequently Asked Questions
Q: Can this enclosure be used in 1000V DC Solar applications?
A: Yes. The enclosure material and insulation properties are rated for high-voltage DC environments, provided the installed breakers are appropriately rated.
Q: What is the benefit of the IK08 rating?
A: The IK08 rating indicates that the enclosure can withstand a 5-joule impact (equivalent to a 1.7kg mass dropped from 300mm), ensuring durability in industrial zones.
Q: Are the internal terminals included?
A: Yes, standard units come equipped with the DIN rail and a set of insulated Earth/Neutral bars.
