This IMST 32A three phase distribution board is a simple, professional way to create multiple safe, protected circuits from a single incoming supply. It is ideal for practical setups where you have a mix of small and mid sized loads, such as temporary work areas, cabins and compounds, exhibition stands, workshop bays, plant rooms, control equipment, and general site power.
Protection
Instead of putting everything behind one device, this unit gives you six separate outlets, each with its own RCBO. That means if one connected item develops a fault or nuisance trip, you only lose that one circuit, not the whole board. It is also a tidy way to avoid background leakage building up across multiple devices and tripping a single shared RCD.
- 4 × 16A outlets, each protected by its own 16A 30mA two pole Type A RCBO (C curve)
- 2 × 32A outlets, each protected by its own 32A 30mA two pole Type A RCBO (C curve)
Phase split (how the load is spread)
To help keep loading balanced across the supply, the outputs are split across phases as follows:
- L1: 1 × 32A
- L2: 1 × 32A + 2 × 16A
- L3: 2 × 16A
Loop through (through supply)
A 32A three phase loop through outlet is fitted so you can continue the supply onwards to additional distribution boards or equipment. This keeps power layouts tidy and makes it easy to add more distribution without extra splitters.
Rugged enclosure
The enclosure is shock resistant polyamide, designed to be tough, lightweight and genuinely portable. It has a folding steel carry handle, a stackable design, and the protective devices sit under a clear window so checks are quick and obvious. Rated IP44, it is suitable for real world temporary use where conditions are not always perfect.
