125Amp 3 Phase Distribution

Our 125A three phase distribution board is built for larger power setups where you need a single incoming supply feeding multiple circuits safely and reliably. It suits site compounds, workshops, plant, industrial maintenance, exhibitions, outdoor installations and temporary power jobs where loads are higher, and the distribution needs to stay dependable.

Unlike many Distribution boards that rely on lightweight moulded housings, this unit uses a hard wearing impact resistant polypropylene enclosure chosen for demanding use, with strong chemical and corrosion resistance. It is designed for real handling and transport, not just sitting in a dry cupboard.

Clear, confidence inspiring indication

Every output has a green LED power indicator so you can see at a glance which circuits are live. A phase rotation indicator is fitted so you can quickly confirm the supply is correct before energising three phase loads.

Transport and handling

Because these boards get moved a lot, it’s fitted with proper carry handles for easier handling on site. The handle design also gives you solid ratchet strap points, making it simple to secure the unit during transport without worrying about the enclosure deforming or warping.

Incoming protection and isolation

The incoming supply is protected by a 125A four pole device providing overcurrent protection and a clear point of isolation for safe working (ideal when the unit is being moved, serviced, or reconfigured).

Single phase outputs, protected properly

All single phase outputs are protected by two pole Type A RCBO protection, giving RCD protection and overcurrent protection in one device. This is the cleanest way to protect individual circuits and helps reduce nuisance tripping on real equipment loads.

Three phase output protection options (depending what you select)

The three phase output can be supplied with different protection options so you can match it to what you are feeding downstream, whether that is a sub board or three phase appliances.

Fixed 30mA RCD option
A good choice where you want straightforward additional protection at the output with a fixed 30mA trip level.

Variable RCD option (without key bypass)
If you select the Variable RCD option, it uses an earth leakage relay with adjustable trip level and time delay, giving you a practical way to suit different loads and site conditions instead of being locked into a single setting.

• Adjustable trip sensitivity from 30mA up to 10A
• Selectable time delay from instantaneous up to 10 seconds (in steps)
  
• Clear indication when bypass is active, so it is obvious what state the protection is in
