Production

Low voltage installations meeting the highest industry standards

Every industrial facility, power plant or infrastructure project requires reliable electrical system solutions.

From the conceptual design to the last cable laid and the tested control cabinet ready for delivery, ATO will carry out the production quickly, transparently, and in accordance with all safety and quality standards.

We have gained our experience over 30 years of work in all branches of industry, especially through work on critical and infrastructure projects. Some with partners, and some on our own, from scratch.

We can also dismantle and dispose current installations, perform any kind of supervision, and implement safety measures in accordance with Croatian or EU standards.

We produce independently, from the ground up.

In our fully equipped and automated production facility we produce:

  • Low-voltage switchgear of all levels of complexity
  • SIVACON S8 low-voltage switchgear up to 7000 A
  • All other types of low voltage electrical cabinets

We also offer additional services that enhance the quality and value of finished products:

  • Parameterization and initial setup of switching and measuring equipment
  • Performing internal or client-specific test protocols
  • Preparation and execution of Factory Acceptance Testing (FAT)
  • Complete delivery logistics: packaging, protection, and truck transport

SIVACON S8 is our first choice

As a main Siemens partner and franchise holder, we have designed, delivered, and installed hundreds of SIVACON S8 systems in critical infrastructure facilities (power generation, transmission, and distribution, oil and gas, and more).

SIVACON enables the functional grouping of equipment, which can be installed as independent units that can be individually connected or disconnected from the system, thereby increasing the availability of the system and the facility as a whole.

Features of SIVACON S8 cabinets :

  • Busbar systems up to 7000A
  • Various types of cabinets (incoming, fixed, withdrawable, disconnect busbars, custom cabinet types)
  • Withdrawable motor and cable feeders
  • High level of reliability, availability, efficiency, quality, and safety
  • High degree of production automation
  • Strictly defined and multi-controlled testing protocols
  • SIMOCODE multifunctional electronic motor protection device with integrated control and diagnostic functions


Final result is always quality!

Every control system we design, implement, and commission, every production line or electrical project, is rigorously tested. There is no room for error.

Testing and commissioning

After assembling and connecting the equipment into a complete system, we will test the functionality of your system under both cold and hot conditions and be by your side during commissioning and the trial operation period.

ATO engineers will test your systems according to your requirements and needs, using proven quality assurance protocols.

The testing steps include:

  • Parameterization of protection devices, process instrumentation, various converters, barriers, soft starters, frequency converters, measuring devices, thermostats, uninterruptible power supplies, etc.
  • Testing of signal circuits from actuators to operator interfaces
  • Control logic tests
  • Sequence tests
  • Measurement and control loops tuning

Commission and forget until the next scheduled maintenance and inspection
