Modular cabinet SMC 1200 – the SMC 1200 is a modular cabinet with 20 modular slots, where the content can be modified according to the needs of the construction site. By selecting only the necessary fuse switches and other components, you can save considerably. The content can be re-edited to fit the next worksite. Unnecessary module slots are covered with cover plates. The cabinet has lifting eyes and the stand is designed for moving with a forklift. The sturdy cabinet, secured with powder-coated aluminium, stands on its own stand. The corrosion-free cabinet withstands heavy handling on site and the components behind locked doors remain safe.

Modular cabinet SMC 1200 on the worksite

The distribution board is the site’s outlet point: power for hand tools, lighting and dryers is taken from it. It is placed close to the work so that extension cords stay short.

Boards are added as the site grows. The whole is worth planning in advance so that the supply is sufficient for all of them.

The product occupies 20 module slots. Module slots are a limited resource, so the configuration is worth planning before ordering.

Where Modular cabinet SMC 1200 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.

Modular cabinet SMC 1200 – 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 Temporary power supply subcabinet 250 A, Sub cabinet 160 A, Sub cabinet TAK 125A KS, Sub cabinet TAK 63 A KS, Subcabinet TAK 32A.

Other details that affect the choice: protection class IP44, short-circuit withstand Icf = 25 kA, weight 86 kg, dimensions 1600×1229×530 mm. These are worth checking already at the quotation stage.

Modular cabinet SMC 1200 – 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.

Modular cabinet SMC 1200 – 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 86 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.

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.
