Perfectly Plugged Electrical Installations – with WINSTA®

The WINSTA® Pluggable Connection System easily meets the strict requirements of building installations. The system provides simple pluggable electrical connections, making electrical installations fast, safe and error-free. This also applies to other applications, such as marine and railway systems, as well as industrial applications.

Benefits in at a Glance:

  • Protected against mismating and maintenance-free
  • Push-in CAGE CLAMP® spring pressure connection technology allows solid conductors to be simply pushed into a unit
  • A wide product range readily meets all electrical installation requirements: plugs, sockets, snap-in device connectors, PCB connectors, as well as distribution connectors, cable assemblies and distribution boxes
  • Compact design
  • Components can be clearly printed on and color-coded to meet custom requirements


WAGO’s WINSTA® Pluggable Connection System allows structured planning and faster completion of projects

WINSTA® allows electrical installations in the areas of energy management, lighting control, and HVAC to be optimized despite increasing complexity.

Conventional Installation vs. Pluggable Installation

The WINSTA® Pluggable Connection System is based on cable assemblies and standard components, which are combined in accordance with the construction project. WINSTA® is the ideal solution anywhere installation requirements repeat or are planned on a grid, e.g., installing grid lighting or flush-mount lighting. By using this pre-assembled connection system, assembly times and installation errors on the construction site can be reduced. And since the individual WINSTA® components are both mechanically coded and color-coded, incorrect connection is impossible.

For Space-Restricted Applications


The WINSTA® MINI family is ideal for pluggable electrical installations in confined spaces. Its compact design supports the trend of downsized components, including LED lights and electronic ballasts.


  • Conductor range: up to 1.5 mm2 (16 AWG)
  • Nominal current: 16 A
  • WINSTA® MINI special components for specialty applications (e.g., measurement, control and regulation technology) with custom printing
  • Compact pluggable PCB connectors are available with 4.4 mm (0.1732 inch) pole spacing

For Maximum Possibilities


The WINSTA® MIDI family offers the greatest diversity of components for fast, reliable and error-free electrical installations. This enables you to individually and flexibly fulfill the most varying requirements.


  • Conductor range: up to 4 mm2 (12 AWG)
  • Nominal current: 25 A
  • Two-wire connection per pole for loops or bridges
  • Easily identifiable through optional customer-specific printing as well as intelligent labeling accessories
  • Additional variable coding is possible
  • Available in 2- to 7-pole configurations
  • Pluggable lighting connection with the universal Linect® Lighting Connection System and WINSTA® Linect® T-Connectors

For Greater Power


The WINSTA® MAXI family includes high-current, pluggable connectors for power supply applications.


  • Conductor range: up to 6 mm2 (8 AWG)
  • Nominal current: 35 A
  • Minimize voltage drop over longer cable runs

For Greater Diversity


The WINSTA® Boxes readily serve diverse applications. For example, WINSTA® Distribution Boxes support the control of several sunblind drives via SMI or the connection of DALI lights. The WINSTA® System Box provides a variety of customizable solutions for applications, such as power distribution, control and switching systems. WINSTA® Boxes are planned and manufactured according to customer requirements by our Project Service division.


  • Compact solution with pluggable outputs
  • WINSTA® Boxes allow centralized, clearly laid-out electrical installations
  • WINSTA® Distribution Boxes are also available for self-assembly
  • WINSTA® System Box: Install DIN-35-rail-mount components, such as circuit breakers, fuses and relays

For Maximum Flexibility


The WINSTA® IDC family consists of flat cables ranging from 1.5 mm2 to 16 mm2 (14–6 AWG) and the associated modules that are compatible with WINSTA® MIDI and WINSTA® KNX Pluggable Connectors and provides power to raised-floor boxes.


  • WINSTA® IDC Supply and Tap-Off Modules allow connection at any location of the flat cable – one rotation per pole is all that is required.
  • Suitable for bus and power lines or for bus and power combined in one cable
  • Easy installation without line interruption due to convenient insulation displacement technology (IDC)

For Round Conduits and Ducts


The WINSTA® RD family of pluggable circular connectors is ideal for installation in cable ducts, e.g., in prefabricated houses. Due to their round design, the WINSTA® RD cable assemblies easily fit into properly sized holes and installation pipes.


  • Conductor range: up to 2.5 mm2 (14 AWG)
  • Nominal current: 16 A/20 A
  • Portfolio of three- and four-pole pre-assembled cables with 17.5 mm (0.0689 inch) outer diameter for easy plug & play
  • Plug-in integration into the electrical installation of hollow-wall boxes via adapter, for example

For the Standardized Bus


WINSTA® KNX is the solution for standardized fieldbus systems in building and industrial automation (e.g., KNX, LON® or ETHERNET).


  • For low voltages up to 50 V
  • Nominal current: 3 A
  • Compact size, standardized interface
  • Available in two different custom coding options with mismating protection

WINSTA® in Building Installations

Click and Done!

WAGO WINSTA® can optimize all your installation processes. The modular, pluggable installation system consists of cable assemblies and standard components. The installation is planned in advance, and the required components and cables are specified and ordered. The electrical components of a project – lights, sockets or climate control systems – can be obtained from WINSTA® system partners with connectors already integrated, or equipped with the appropriate WINSTA® Plugs independent of the construction site. At the construction site, everything can then be plugged in quickly and reliably.

Straightforward Building Installation

Whether an administrative building, school or hospital – many such functional buildings follow a standardized pattern with repeating tasks. That’s exactly what the WINSTA® system is designed for. Furthermore, the modular structure of WINSTA® allows tasks to be processed in stages, optimizing personnel deployment at construction sites.

In the first stage, WINSTA® Distribution Boxes are installed. This can already be done in an early construction phase. In the second step, the electrical components are connected to the distribution boxes with the cable assemblies. This can be done at a later point, for example in order to protect lights from contamination during the construction phase. Furthermore, pluggable installation allows flexible coordination when their are scheduling overlaps with work on other building systems.

WINSTA® also has advantages for sustainable electrical installation, since what has been installed with the modular system can be easily modified or expanded at any time. In summary: Using WINSTA® allows you to make the best arguments in your bids, since you can provide sustainable quality in an economical way.
