Shop floor of Elpro GmbH

On more than 4,000 m2 of shop floorspace, we produce ready-to-connect, fully wired and function-tested electrical engineering products for the following applications:

Low-voltage switchgear

Niederspannungs-Schaltanlage ENSaS 5000

Niederspannungs-Schaltanlage ENSaS 5000

Based on in-house developments, as a license partner, and to customer specifications, we project-manage and manufacture switchgear with:

  • Rated operating voltages up to 690 V AC
  • Nominal current up to 6300 A
  • Rated short-circuit current up to 160 kA lcw (1s)
  • Infeeds, couplings, and taps
  • Hardwired, insert, and withdrawable design configurations
  • Protection type up to IP54 
  • Cable and/or rail connections from below/overhead.

We optimize our solutions based on the manufacturer-independent use of electrical operating equipment and the unrestricted selection of the housing system.

Mid-voltage switchgear

Mittelspannungs-Schaltanlage

Mittelspannungs-Schaltanlage

We project-manage, fabricate, and supply MV installations for

  • power plants
  • substations
  • switching stations
  • industrial plants of all types
  • MS utility grids of the power utilities.

The primary components are project-managed and manufactured in collaboration with our system partners ABB and Scheider Electric. Our in-house operations finalizes the controller, the installation protection, and the control systems integration, including all testing, assembly, and commissioning .

DC switchgear

Gleichspannungs-Schaltanlage

With regard to railway power supply, we produce and deliver DC switchgear for public regional commuter railways.

For rectifier sub-stations, we manufacture:

  • station service plants
  • Rectifiers
  • DC switchgear panels
  • High-speed switch modules (HSSM)

Elpro products are intended for use in  railway power supply installations with a nominal voltage of 750 V DC and 3000 V DC.

Automation and protection technology

On various system platforms, we manufacture systems for instrumentation and control engineering:
