Small complete distribution boxes are compact electrical enclosures designed to safely distribute power, featuring modular configurations, IP-rated protection, and options for surface or flush mounting.

General Features

Small distribution boxes are designed for residential, commercial, and light industrial applications. They typically include: Material: High-grade thermoplastic or metal construction for durability and electrical safety. Protection Rating: IP30 to IP65 depending on model, ensuring protection against dust and water ingress.

Mounting Options: Surface-mounted or flush-mounted configurations to suit installation requirements. Circuit Capacity: Ranges from 1-way to 36-ways, accommodating various numbers of MCBs, RCDs, or MCCBs. Amperage Ratings: Typically from 32A to 125A, depending on the application and number of circuits.

Safety and Functional Features

Modern small distribution boxes incorporate advanced safety and operational features: Residual Current Protection (RCCB/RCD) to prevent electric shock. Surge Protection to safeguard connected equipment from voltage spikes. Proper Earthing Systems for electrical safety.

Busbar and Terminal Shrouding to prevent accidental contact and hot spots. Modular Design allowing easy addition or replacement of MCBs and other components without obstructing existing circuits.

Dimensions and Design

Compact Size: Designed to save space while providing sufficient wiring room. Front Cover and Door: Often includes transparent windows for easy inspection and screws located behind the door for added security. Flexible Wiring Space: Adjustable studs and nuts for easy mounting and removal of internal components.

Labeling Options: Transparent shrink sleeves or labeling areas for circuit identification. Product ExamplesABB Mini Center Compact: Offers multiple incomer options (Switch Disconnector, MCCB, MCB, RCCB) with modular DIN rail components. Eaton xComfort BF Series: Includes surface-mounted and flush-mounted boxes with IP30 protection and Class II insulation for most models.

Distro-

Direct Type 10/11 Series: Modular small distribution boxes with various input/output configurations and optional protective breakers.

Additional Considerations

Compliance Certifications: Ensure boxes meet local electrical standards and safety regulations. Accessories: Blanking plates, cable entry systems, and extension boxes are often available to customize installations. Bulk Purchase Options: Many suppliers offer cost savings for large-scale projects.

These specifications make small complete distribution boxes a versatile and safe solution for managing electrical power in compact installations, providing flexibility, protection, and ease of maintenance.
