Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 is a floor distribution board with a fixed cable input, where per-phase meters show the current and voltage of each of the three phases. The meters also double as indicator lights that show current is reaching the phases.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 – fixed input makes the board more reliable

A fixed input makes the board more reliable than a plug-connected board: the supply can’t be accidentally disconnected, stolen or moved. The board is versatile, since it can be fed with a fuse rated anywhere from 63–125A depending on what’s needed.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 – emphasis on 32A outputs

Outputs include 1×63A, 3×32A, 1×16A and 2×16A/230V. Three 32A outputs make this board a particularly good choice when several medium-sized machines are used on site at the same time — for example mixers, compressors or heaters.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 – the final board in the chain

Unlike the base model, this board cannot chain power onward to another board — all power leaves through the socket outputs. Version 2 is therefore meant to be the last board in a line, once no further chaining is needed. On this model, the phase meters measure only the socket outputs.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 – phase meters reveal unbalanced load instantly

Per-phase measurement helps you spot unbalanced load before it trips a fuse or causes a break in the site’s power distribution. Read here why and how phase measurement makes site operations more efficient.

A light aluminium body that travels well

the product is made of aluminium, so it’s light in construction. It’s easy to carry by its handle and hang on a wall or board stand from the hanging loops, or it can be set on the floor on its own feet.

Serviceable and customizable

The board is manufactured in Finland using only high-quality European components, such as PCE and Schneider. All parts are available as spare parts, and the board can be modified according to customer wishes — for example, the number and size of the boxes can be changed.

How version 2 differs from the other floor distribution boards

Version 2 is meant to be the last board in a chain — it cannot chain power onward. If you need a board you can chain onward from, see the base model or version 4.

Who this floor distribution board suits

the product suits large projects and sites in particular, where many boards are needed and this board serves as the last link in the chain, once sufficient power along the route has already been ensured with 125A cabling. The “floor” in this board’s category name doesn’t mean it has to be used per building floor — a “floor” can just as well be any area or point in the chain. The model also suits multi-storey sites where several medium-sized machines run at the same time and this board is the last one in the chain, with no need to continue onward.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 on the worksite

A floor distribution board brings power to where the work is done. Placed on the working floor, it removes the need to run extension cords through stairwells.

Short cords are both a safety and a quality matter: a long cord causes voltage drop and is a permanent trip hazard.

This model is rated 125 A. Size the equipment by the actual simultaneous load – the sum of the nameplate ratings almost always leads to oversizing.

Outputs: 1×63A, 3×32A, 1×16A, 2×16A 230V. Count the work points before choosing – the number of outputs decides how many machines one board can feed.

Where Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 is used

Typical sites are construction projects, renovations, industrial maintenance and event power. What they share is that the electrical supply is temporary and the conditions are demanding.

Temporary does not mean lighter requirements. Site equipment is exposed to dust, moisture, moving and mechanical stress in a way that fixed installations never are.

Check the load distribution between phases during use. Uneven distribution overloads one phase while the others run half empty, and the usual symptom is a fuse that keeps tripping.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 – how to choose the right model

The equipment is chosen by rated current and outputs. Start by calculating the simultaneous load and the output types needed, and choose the model on that basis.

Other models of the same type are Subcabinet for floorlevels TAK 63/100A, Subcabinet for floorlevels TAK 63/100A PRO KS, Fixed input floor distribution board 63A/125A/VM chaining 125A, Fixed input floor distribution board 63A/125A/VM fixed 32A outputs, Fixed input floor distribution board 63A/125A/VM fixed 32A + 63A outputs.

Other details that affect the choice: protection class IP44, RCD 1 x 40A/30mA, 2 x 63/300mA, weight 17,8 kg, dimensions 22×46×82 cm. These are worth checking already at the quotation stage.

Practical notes for use

Winter brings requirements of its own. Condensation forms when cold equipment is brought into the warm, and moisture inside the enclosure is a common reason for an RCD tripping with no visible cause.

Mark the equipment with the site details and keep a record of what is fed from where. On a site with several contractors that saves time at every fault-finding.

RCD protection is mandatory for socket outputs on a site. Its operation is tested with the test button at commissioning and at regular intervals afterwards.

Distribution center with fixed input and phase load measurement TSR 63/125A ver 2 – installation and maintenance

Installation and connection work is carried out by a qualified electrician. The equipment must be made dead before connection work, and the absence of voltage verified by measurement.

Place the equipment on level ground and so that it can be reached freely even when the site fills up with material. Material stacked in front blocks both use and emergency isolation.

Test the RCD with its test button at commissioning and at regular intervals afterwards. The test takes a second and is still almost always forgotten.

The unit weighs 17,8 kg. Take the weight into account when moving and lifting – damage is most often caused during transport, not in use.

Check the joints and fixings regularly during use. A joint that heats up is a sign of a fault and should be corrected before the fault spreads.

Safety and inspections

Site electrical installations are subject to the same requirements as fixed installations, and some of them are stricter. The equipment has to withstand moving, dust, moisture and mechanical stress for the whole project.

The installation is inspected at commissioning and regularly during use: enclosure, joints, the operation of the protective devices and the fact that live parts cannot be reached.

Damaged equipment is not repaired improvised on site. A cracked enclosure, a burnt terminal or a damaged socket is replaced – on a site a temporary repair almost always becomes permanent.

Document the configuration and any changes made. Up-to-date information on outputs and protection speeds up fault-finding and the next inspection.

Delivery and sizing help

We deliver the equipment together with the cables and the rest of the site power supply in one delivery, so the set is complete when it arrives on site.

Describe the whole site in your request for quotation: supply power, the outputs needed and the estimated length of the project. We size the set on that basis.

Use the product number 5000334/2 when ordering and when asking about spare parts. It identifies this exact model, which matters when the same series comes in several sizes.

We also help with the sizing. If you are unsure about the size or the number of outputs, ask us – equipment sized wrong costs more than equipment chosen right the first time.
