IMST 32Amp Three Phase Thru to 2 x 32Amp, 4 x 16Amp MCB

This IMST 32A three phase distribution board is a simple, professional way to create multiple 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 with individual overcurrent protection on each circuit:

• 4 × 16A outlets, each protected by its own 16A MCB (Type C)
• 2 × 32A outlets, each protected by its own 32A MCB (Type C)

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

That means if one circuit is overloaded or develops a short circuit, only that output trips, helping keep the rest of your setup running.

Because this model is MCB only, it provides overload and short circuit protection on each output, but it does not provide 30mA RCD personal protection at the outlets. It is best used where the upstream supply already provides the required RCD protection, or where RCD protection is managed elsewhere in the system.

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.
