Malawi Level 3 Distribution Box Dimensions and Specifications

Malawi Level 3 Distribution Boxes are typically outdoor LT cabinets fabricated from 2 mm GI sheet steel, with IP-55 protection, reinforced structure, and configurable busbar and MCCB arrangements.

Construction and Material

Level 3 distribution boxes in Malawi are generally outdoor-type cabinets made from 2 mm galvanized iron (GI) sheet steel with reinforced channels for structural stability. The roof is slightly slanting with a 50 mm overhang to prevent water ingress. Doors are equipped with Godrej-type 3-position locking systems, and hinges are concealed to enhance security.

The boxes include solid earthing points on either side and are designed to withstand environmental exposure while maintaining IP-55 protection.

Dimensions

The exact dimensions may vary depending on the manufacturer and capacity, but typical illustrative dimensions for LT distribution boxes are provided with a tolerance of ±10%. Standard boxes accommodate 1-way to 36-way configurations, with length, width, and height specified according to the number of outgoing feeders and MCCB arrangements. Internal space is sufficient to allow busbar placement, cable entry, and clearance for heat dissipation.

Electrical Specifications

Busbars: EC grade aluminum or copper flat strips, typically 25x4 mm for phase connections, with heat-shrinkable or color-coded insulation (Red, Yellow, Blue, Black) between phases.

MCC

Bs: One 4-pole MCCB for incoming supply and 1 outgoing feeder arrangement with 2 sets of 3-pole MCCBs.

MCC

Bs conform to IS: 13947 standards with magnetic trip release and manual resetting. Isolators: Switch disconnectors with 80 kA breaking capacity, arc-chutes with minimum 12 strips, and handles of minimum 3 cm length on cable connection side. Cable Entry: Heavy-duty, double-compression brass cable glands for incoming and outgoing cables, with detachable plates for fixing.

Additional Features

Phase sequence: RYB maintained throughout the box. Porcelain cutouts: Provided in higher capacity boxes (160 KVA / 315 KVA) for outgoing circuit protection. Identification: Non-detachable nameplates and punch marks for purchaser identification.

Lighting provision: Some boxes include internal lighting for maintenance. These specifications ensure that Malawi Level 3 distribution boxes meet safety, operational, and durability standards suitable for low-tension (LT) distribution networks. Manufacturers may provide detailed drawings and exact dimensions based on the number of ways and KVA rating required.
