The TBC-WD18 is a 18-way waterproof distribution box designed to deliver dependable enclosure protection for circuit breakers and associated distribution equipment across a wide range of installation environments. Built to an IP65 protection rating, it effectively guards against dust ingress and low-pressure water jets, making it equally suited for indoor utility rooms and exposed outdoor locations.

Constructed from a flame-retardant, UV-resistant housing material, the TBC-WD18 maintains structural integrity under prolonged sun exposure and elevated thermal conditions. Its transparent cover allows visual inspection of installed devices without the need to open the enclosure, reducing maintenance downtime and improving operational safety.

Targeted at electrical contractors, panel builders, and system integrators, the TBC-WD18 combines a compact modern footprint with practical installation features — including a 35 mm DIN rail mount and easy cable entry points — to streamline deployment across residential, commercial, and light industrial projects.

Key Features

  • IP65 Waterproof Rating: Provides full protection against dust ingress and low-pressure water jets for reliable outdoor and indoor use.
  • 18-Way Capacity: Accommodates up to eight standard DIN-rail-mounted circuit breakers or modular devices within a single compact enclosure.
  • Transparent Cover: Allows visual inspection of installed breakers and indicator status without opening the enclosure, enhancing operational convenience and safety.
  • Flame-Retardant Housing: Enclosure material meets flame-retardant requirements, limiting fire propagation risk in the event of an electrical fault.
  • UV-Resistant Material: Housing is formulated to resist degradation from prolonged ultraviolet exposure, ensuring long service life in outdoor installations.
  • 35 mm DIN Rail Mounting: Compatible with standard 35 mm DIN rail, enabling quick and secure installation of modular electrical devices.
  • Easy Cable Entry: Pre-designed cable entry points simplify wiring and reduce installation time on site.
  • Durable Locking Design: Secure locking mechanism on the cover prevents unauthorised access and maintains enclosure integrity under operational conditions.
  • Compact Modern Design: Space-efficient dimensions suit installations where panel space is limited, without compromising on device capacity.
  • Dual-Environment Suitability: Engineered for both indoor and outdoor deployment, reducing the need for separate enclosure specifications across different project types.

The TBC-WD18 Waterproof Distribution Box is purpose-built to house and protect miniature circuit breakers and other modular DIN-rail devices in environments where exposure to moisture, dust, and UV radiation is a concern. Its IP65-rated enclosure ensures that neither dust particles nor directed water jets can compromise the integrity of the installed electrical components, making it a dependable choice for outdoor switchboards, garden lighting circuits, solar PV combiner applications, and water pump control stations.

The enclosure body is manufactured from a high-quality flame-retardant thermoplastic that resists UV-induced embrittlement and discolouration over extended service periods. The transparent polycarbonate-style cover provides a clear view of installed devices and their trip status, allowing maintenance personnel to assess circuit conditions at a glance. The durable locking mechanism secures the cover firmly, preventing accidental opening and deterring unauthorised interference.

With overall dimensions of 188 × 90 × 356 mm, the TBC-WD18 maintains a compact profile that integrates neatly into surface-mounted or recessed installations. The internal 35 mm DIN rail and thoughtfully positioned cable entry points ensure that wiring is organised, accessible, and compliant with professional installation standards.

The TBC-WD18 enclosure is constructed around a rigid flame-retardant thermoplastic body rated to IP65 in accordance with standard ingress protection classifications, providing a sealed environment for up to five modular DIN-rail devices. The 35 mm DIN rail is factory-fitted within the enclosure, offering a secure and standardised mounting platform compatible with the full range of modular circuit protection devices. Cable entry is facilitated through dedicated knock-out or pre-formed entry points positioned to allow clean, strain-relieved cable routing into the enclosure interior.

The UV-stabilised housing compound is selected to withstand prolonged outdoor exposure without significant mechanical or aesthetic degradation. The transparent cover is retained by a robust locking latch system that maintains the IP65 seal integrity when closed, ensuring that the enclosure continues to meet its rated protection level throughout its operational life. Dimensions of 188 × 90 × 356 mm have been optimised to balance internal device capacity with an externally compact footprint.

  • Residential Buildings: Surface-mounted sub-distribution point for garden circuits, outdoor lighting, and external power outlets at domestic properties.
  • Commercial Buildings: Weatherproof circuit protection enclosure for rooftop plant areas, car park lighting circuits, and external signage power supplies.
  • Outdoor Electrical Systems: General-purpose weatherproof housing for circuit breakers serving any exposed outdoor electrical installation.
  • Garden and Landscape Lighting: Compact distribution point for controlling and protecting multiple garden lighting circuits from a single weatherproof enclosure.
  • Solar PV Systems: Housing for DC or AC circuit breakers within small-scale solar photovoltaic installations requiring outdoor-rated enclosures.
  • Industrial Control Panels: Supplementary weatherproof enclosure for auxiliary control circuits in light industrial or process environments.
  • Water Pump Control: Protective housing for circuit breakers and control devices associated with irrigation pumps, borehole pumps, and water feature systems.
  • Distribution Boards: Sub-enclosure or satellite distribution point feeding branch circuits from a main distribution board in multi-zone installations.
