About us

GJA ELEKTROANLAGEN GmbH develops and manufactures low-voltage switchgear, control cabinets, control systems, scaffolding distribution boards and electrotechnical assemblies in Pfullendorf. The service portfolio covers switchgear up to 4000 A, energy metering and conversion systems, installation distribution boards, industrial control systems, frequency inverters and drive controls, as well as custom cabinet solutions including sheet metal processing and switchgear assembly. For renewable energies, the company manufactures photovoltaic generator metering cabinets, grid connection boxes (NA boxes) and systems with NA protection in accordance with VDE AR-N 4105 and 4110; in addition, LV distribution boards for e-mobility and charging stations are produced. Circuit diagram creation is carried out with EPLAN P8 2024; outgoing feeders can be installed metered or unmetered, which is gaining importance in the context of the new regulation of § 14a EnWG. The team of electronics specialists accompanies projects from planning and design to assembly at the company's own plant. Customers include energy suppliers, municipal utilities, industrial companies, public infrastructure, commercial customers and private residential buildings.
