Subcabinet with fixed input TSR 63/125A Spine is a 63A fixed-input floor distribution board with per-phase meters. The per-phase meters measure the current and voltage of each of the three phases. The meters also double as indicator lights that show current is reaching the phases.

Can be chained onward at 125A to other floors

125A can be chained onward to other floors through the bottom of the board.

Light aluminium construction

The board is made of aluminium and has a light construction. It’s easy to carry by its handle and hang on a wall or board stand from the lifting loops. The board can also be placed on the floor on its feet.

Quality components, customizable

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

Spine remote monitoring and VM phase meters as standard

The board comes with real-time Spine remote monitoring as standard, letting you measure energy consumption and set up proactive alarms, among other things. Setting up the Spine service is easy and quick with a QR code. The board also has VM phase meters, which measure the voltage and current of all three phases and so help avoid unbalanced load.

Subcabinet with fixed input TSR 63/125A Spine on the worksite

Spine is a remote monitoring system. Measurement data is sent to the cloud service where it can be viewed on any device – nobody needs to travel to the site to read a meter.

The service shows electricity consumption, load distribution between phases, voltage drop and CO₂ emissions, among others. Predictive alarms can be set so a deviation is caught before it stops the work.

The same cloud service gathers every Spine unit on the site into one view, however many measuring points there are.

This model is rated 63 A. Size the equipment by the actual simultaneous load – the sum of the nameplate ratings almost always leads to oversizing.

Outputs: 1 x 63A, 2 x 32A, 1 x 16A, 6 x 16A 230V. Count the work points before choosing – the number of outputs decides how many machines one board can feed.

Where Subcabinet with fixed input TSR 63/125A Spine 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.

Subcabinet with fixed input TSR 63/125A Spine – 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 Spine Plug & Play 16A, Spine Plug & Play 32A, Spine Plug & Play 63A, Spine Plug & Play 125A, Spine for 16A-1250A centers with fixed input.

Other details that affect the choice: protection class IP44, RCD 1 x 40A/30mA, 2 x 63/300mA, weight 14,3 kg, dimensions 46x37x22 cm. These are worth checking already at the quotation stage.

Subcabinet with fixed input TSR 63/125A Spine – 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.

Subcabinet with fixed input TSR 63/125A Spine – 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 14,3 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.

Subcabinet with fixed input TSR 63/125A Spine – 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 505010009 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.

Frequently asked questions

How do the VM phase meters help prevent unbalanced load?

The phase meters measure each phase’s current and voltage separately and double as indicator lights. This makes it easy to distribute the load evenly across the phases, which prevents unbalanced load and unnecessary fuse trips.

Can the board’s configuration be customized?

Yes. The number and size of outlets and boxes can be customized to the customer’s needs, and all parts are available as spare parts.

Does the board include Spine remote monitoring?

Yes, as standard. The Spine system lets you measure energy consumption, set up proactive alarms and monitor the electrical network’s status remotely. Setup is done with a QR code.

What is the product’s part number?

The part number is 505010009. You can use it for orders and quote requests.
